r600: Disable eight bit three channel formats

Browse source 
Commit 0899bf55 made some deqp-gles3 tests related to RGB8 PBOs fail
on R600 because it exposed PIPE_FORMAT_R8G8B8_UNORM and R600 doesn't
propely handle this. Disabling this format also for buffers fixes the
issue.

In addition, disabling also the related RGB8 integer formats for buffers
fixes some deqp-gles3 tests:
