glamor_egl: Always require the gbm-based image import path.

Browse Source 
This has been associated with dri3 for now, but we need to use it
elsewhere in order to avoid flink.  The extensions have been
implemented for long enough that I couldn't find when it was that we
turned them on.  Oddly, we already required renderbuffer import
support, which is basically as hard to implement as texture import.
