glamor_egl: Reject OpenGL < 2.1 early on
The Etnaviv driver on GC2000 reports desktop OpenGL 1.3 but also OpenGL ES 2.0.
However, with the modesetting driver, GLES2 never gets a chance:
[ 11233.393] Require OpenGL version 2.1 or later.
[ 11233.393] (EE) modeset(0): Failed to initialize glamor at ScreenInit() time.
[ 11233.393] (EE)
Fatal server error:
[ 11233.395] (EE) AddScreen/ScreenInit failed for driver 0
Let's reject old desktop GL early on, just like XWayland seems to do.
This is perhaps a slightly bit more complicated that one would expect, since we
need to call eglMakeCurrent() before we query the GL version.
