etnaviv: Fake occlusion query capability

Browse source 
This enables the PIPE_CAP_OCCLUSION_QUERY capability without adding an
occlusion query type.

This is necessary to get Mesa to report desktop GL 2.0 support (to run
exciting things such as ioq3's OpenGL 2 renderer), and should be valid
because exposing the capability does not guarantee that any
counters are actually implemented.
