continuation of #109595
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.
* hyperscan: 5.1.0 -> 5.1.1
* provide misc utils needed by build
* hyperscan: build shared libs only by default
Only consumer now (rspamd) needs only the shared libs
+ add a switch to build both shared and static if needed
+ cleaner outputs (previously there was static lib and symlink to shared lib in $dev)
+ fix pkgconfig template for v5.1.1 otherwise "includedir" path is wrong
* hyperscan: restrict to x86_64-linux
Fails to find 'nm' on x64 darwin
