Upstream effectively puts "-lprotobuf -lprotoc" as linking flags, while in fact
"protoc.a" depends on "protobuf.a", so flags should be in reverse order.
It is simpler to append one more "-lprotobuf" than to make patch to fix order.
That means that linker will scan "protobuf.a" twice, but price is neglectable.

pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
