    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:
