*gl-surface-source crashes on Xvfb

Description
When cairo is built with --enable-gl and new references on Xvfb, the only thing preventing the xcb target from passing make check is these tests crashing:
$ grep CRASH test/test-suite.log gl-surface-source: CRASH! egl-surface-source: CRASH!
These pass:
gl-device-creation-changes-context: PASS gl-oversized-surface: PASS egl-oversized-surface: PASS
They don't crash when run on a regular X server with gl capabilities.
