[PATCH xserver] glamor: update "required EGL extensions" comment

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

The extensions listed have not been needed in a while. Replace with the
only remaining requirement.

Decided to keep KHR_gl_texture_2D_image as-is (as opposed to respinning
the other patch I've just sent) since the hunk is badly outdated anyway.
Can split/squash if people prefer.
