st/xlib: Do minimal version checking in glXCreateContextAttribsARB.

The current version checking is wrongly refusing to create 3.3 contexts;
unsupported version are checked elsewhere; and the DRI path doesn't do
this sort of checking neither.

This enables piglit glsl 3.30 tests to run without skipping.
