backend-glx: Fix glXQueryVersion test
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)
