Add media-libs/cogl tweaked to be buildable without mesa on RPi

Allows building cogl without virtual/opengl with USE="-opengl gles2" and
adds USE=rpi for choosing raspberrypi-userland as gles2 provider.
Not runtime tested.
Probably should have a REQUIRED_USE on requiring either one of USE opengl, gles2 (or both)
