[PATCH xserver] glamor: Disable debugging messages other than GL API errors

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

According to Nicolai Hähnle, the relevant specification says "All
messages are initially enabled unless their assigned severity is
DEBUG_SEVERITY_LOW", so we need to explicitly disable the messages we
don't want to get. Failing that, we were accidentally logging e.g.
shader stats intended for shader-db.
