mesa: Handle pbuffers in desktop GL framebuffer attachment queries
Once again, we were handling back-to-front in the GLES3 case, but not
the desktop GL case.
Fixes GTF-GL46.gtf30.GL3Tests.framebuffer_srgb.framebuffer_srgb_default_encoding when run with --deqp-surface-type=pbuffer --deqp-gl-context-type=egl.
