GL: Relax multisampling constraints on visual 

All visuals with parameter GLX_SAMPLE_BUFFERS_ARB = 0 have
GLX_SAMPLES_ARB = 0, so the old code would only ever choose
visuals with GLX_SAMPLE_BUFFERS_ARB>=1 and GLX_SAMPLES_ARB>=1.
Some drivers do not export any multisampling capable visuals,
so dolphin fails to find a matching visual and falls back to
the single buffered visual(which does not work for some yet
unknown reason). Fixes issue #2647.
