3429594114 lib.fileset: Fix tests on Darwin, more POSIX
This was found when trying to run the fileset tests on Darwin
(https://github.com/NixOS/nix/pull/9546#issuecomment-1967409445), which mysteriously fail on Darwin:

  test case at lib/fileset/tests.sh:342 failed: toSource { root = "/nix/store/foobar"; fileset = ./.; } should have errored with this regex pattern:

  lib.fileset.toSource: `root` \(/nix/store/foobar\) is a string-like value, but it should be a path instead.
  \s*Paths in strings are not supported by `lib.fileset`, use `lib.sources` or derivations instead.

  but this was the actual error:

  error: lib.fileset.toSource: `root` (/nix/store/foobar) is a string-like value, but it should be a path instead.
      Paths in strings are not supported by `lib.fileset`, use `lib.sources` or derivations instead.

After dissecting this, I find out that apparently \s works on Linux, but not on Darwin for some reason!

From the bash source code, it looks like <regex.h> with `REG_EXTENDED` is used for all platforms the same,
so there's nothing odd there.

It's almost impossible to know where <regex.h> comes from,
but it looks to be a POSIX thing.

So after digging through the almost impossible to find POSIX specifications
(https://pubs.opengroup.org/onlinepubs/007908799/xbd/re.html#tag_007_003_005),
I can indeed confirm that there's no mention of \s or the like!

_However_, there is a mention of `[[:blank:]]`, so we'll use that instead.

6558e89177 lib.fileset.gitTracked: Allow clones of shallow repositories
The only reason shallow clones are not the default in
`builtins.fetchGit` is that `revCount` can't be provided when cloning a
shallow repository. However, `revCount` isn't used or exposed by
`lib.fileset`. Hence, allowing cloning shallow repositories makes
`gitTracked` more general without any drawbacks.

1c3eb9eff1 lib.fileset.fileFilter: Restrict second argument to paths
While this change is backwards-incompatible, I think it's okay because:
- The `fileFilter` function is not yet in a stable NixOS release, it was only merged about [a month ago](https://github.com/NixOS/nixpkgs/pull/257356).
  - All public uses of the function on GitHub only pass a path
- Any `fileFilter pred fileset` can also be expressed as `intersection fileset (fileFilter pred path)` without loss of functionality.
  - This is furthermore pointed out in the new error message when a file set is passed

2035f8a324 lib.fileset.fileFilter: Don't run predicate unnecessarily
Before:

    nix-repl> fileset.trace (fileset.fileFilter (file: builtins.trace file.name false) ./default.nix)
    trace: README.md
    trace: benchmark.sh
    trace: default.nix
    trace: internal.nix
    trace: mock-splitRoot.nix
    trace: tests.sh

After:

    nix-repl> fileset.trace (fileset.fileFilter (file: builtins.trace file.name false) ./default.nix)
    trace: default.nix

0ace383438 lib.fileset: Make error messages more uniform
Just minor changes like:
- Always using "X is a Y, but it should be Z"
- "X is a path that does not exist" rather than "X does not exist"
- Always using multi-line strings for errors
- Always quoting string-like values and not quoting path-like values
  - But do quote filesystem roots. Even though they're paths, they might
    be very small, good to have quotes to know the start/end
- Capitalise the first word
- Distinguish root vs filesystem root more
