package/libglib2: fix util-linux dependency

Replace util-linux dependency by util-linux-libs to break the following
circular dependency:

 util-linux -> udev -> systemd -> polkit -> libglib2 -> util-linux

which will result in the following build failure:

../output-1/build/libglib2-2.64.4/meson.build:1931:2: ERROR: Dependency "mount" not found, tried pkgconfig

This will also raise the following build failure with util-linux:

checking for udev_new in -ludev... no
configure: error: udev selected but libudev not found
