[gdk-pixbuf] meson: Use convenience functions for compiler checks

[Emmanuele Bassi <ebassi src gnome org>]

    meson: Use convenience functions for compiler checks
    
    Avoid a bunch of array iterations.
    
    The get_supported_link_arguments() call is gated on a Meson version
    check, to avoid requiring a bleeding edge stable version.
