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.
* pass IOKit to libfido2
* Add a patch so that cmake uses lld flags when linking
* Upgrade from 1.3.0 to 1.3.1 (based off #80781)
* Specify CMAKE_INSTALL_LIBDIR so that the demo binaries link
correctly on macOS and libfido2.pc specifies correct arguments
