make-squashfs: use __structuredAttrs
Makes it easier to enable discarding of references, a feature of Nix

eea6baad50 make-squashfs: use $NIX_BUILD_CORES or 48 cores if above 48
by default all cores are used

hoping this will fix the hydra i686 squashfs build issues as all the
failures were using 64 cores

Parallel mksquashfs: Using 64 processors
Creating 4.0 filesystem on ..., block size 1048576.
FATAL ERROR: mangle2:: xz compress failed with error code 5

squashfs: use -no-hardlinks for reproducible squashfs images (#114454)
the nix store may contain hardlinks: derivations may output them
directly, or users may be using store optimization which automatically
hardlinks identical files in the nix store.

The presence of these links are intended to be a 'transparent'
optimization. However, when creating a squashfs image, the image
will be different depending on whether hard links were present
on the filesystem, leading to reproducibility problems.

By passing '-no-hardlinks' to mksquashfs the files are stored
as duplicates in the squashfs image. Since squashfs has support
for duplicate files this does not lead to a larger image.

ISO images: Initialize the Nix database with correct NAR hashes/sizes
The boot test now runs "nix verify" to ensure that all hashes are
correct.

897b10998b Tune mksquashfs for smaller isos.
Bigger block size, more suitable for xz.
