`grandorgue` failed to build because GCC 13 stopped transitively
including some headers like `cstdint` in a lot of situations,
leading to many references to types like `uint8_t` in old C++
code breaking unless the respective include statements were

pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans

moves the entry to aliases.nix.

it's the canonical name of the upstream package
on pypi.
