Fixes the evaluation of packages in pkgs/os-specific/windows that
weren't updated to include a new lib parameter after the refactor from
stdenv.lib -> lib (#109490).
I originally only intended this change to fix
`pkgsCross.mingw32.buildPackages.gcc` & `pkgsCross.mingwW64.buildPackages.gcc`
to support building wine with `mingwSupport`, but I noticed this was
an issue for all updated windows packages. Most of these other
packages fail to build for other reasons.
