Meson: Simplify pkgconfig file generator

Meson knows all private dependencies itself when passing the library as
first positional argument, no need to specify them manually. Also
simplify backend specific files by simply requiring gtk4, just like
unix-print already did.

This should fix generated gtk4-uninstalled.pc, see Meson bug report:
