e - comp - wl - fix garbage pixles on rpi4 - properly do fmts/mods

we didnt properly do formats/modifiers. this meant that qwhen
something like the rpi4 started using interesting ones we ended up
with garbage pixels. this fixes that - uses new evas gl feature so
will need efl git master and eventiually efl 1.26 (already do anyway)

@fix
