Test for GL_EXT_bgra in addition to GL_EXT_texture_format_BGRA8888

Some drivers don't expose the OpenGL ES extension GL_EXT_texture_format_BGRA8888, but its OpenGL superset GL_EXT_bgra.
The cairo-gl context initialization will fail for OpenGL ES if that is the case, as cairo checks only for the existance of the GL_EXT_texture_format_BGRA8888. The initialization fails even when the functionality is present on the device.

The same issue was reported/fixed in webkit/chromium:
