gegl: upgrade 0.3.18 -> 0.4.20

* gegl is GPLv3 now
* gegl moved to meson build
* move to meta-gnome: latest gimp requires gexiv2 and nothing but gimp depends
  on gegl
* add more PACKAGECONFIGs and change defaults slightly: sdl->sdl2 / add gexiv2
  by default because gimp requires it anyway
* extend to native: latest gimp requires gegl for manipulation of pngs during
  build
* get sources from location gimp's homepage suggests
