gallium/dri: Factor out DRI extension setup code

Browse Source 
Share the DRI extension setup code between
dri2_init_screen and dri_kms_init_screen. There's
currently very little difference, and the sharing
will make a subsequent change to refactor this
code to use per-screen extension lists easier.
