Fork: Skip sharing GL_LUMINANCE textures
Due bugs in some drivers, sharing GL_LUMINANCE fails and causes causes a
NPE crash. WebRTC is the only feature using GL_LUMINANCE textures which
do not require to be shared, so skip them altogether.
Forking because situation in trunk has changed significantly and this is
no longer appropriate.
