[grilo] build: generate .pc files

[Victor Toso <victortoso src gnome org>]

commit 846d1868f83b29e5addb1fec0cd210104e6b735a

    build: generate .pc files
    
    The generated .pc have been kept essentially identical
    to the original ones with the same variables.
    
    To squash warnings the meson_version was also bumped

 grilo-net-0.3.pc.in         | 15 ---------------
