backend-glx: Fix glXQueryVersion test

Browse Source 
This fixes some backwards logic for asserting that we have a GLX major
version == 1 and a minor version >= 2. (NB: Although we technically
depend on GLX 1.3 features, we still have to support drivers that report
GLX 1.2 because there are a lot of mesa drivers out there incorrectly
report GLX 1.2 even though they export extensions that depend on GLX
1.3)
