egl/glx: Remove egl_glx driver
Mesa now has a real, feature-rich EGL implementation on X11 via xcb.
Therefore I believe there is no longer a practical need for the egl_glx
driver.
Furthermore, egl_glx appears to be unmaintained. The most recent
nontrivial commit to egl_glx was 6baa5f1 on 2011-11-25.
Tested by running weston-smoke in windowed Weston on X with i965.
