glhd: Add test for logicop enable.

Only for first RT at the moment, as there is no trivial way in galahad
to look at framebuffer state and (sadly) people don't usually calloc
their CSOs, so flags could be wrongly set.

On the other hand, of course, galahad will hopefully encourage more
people to calloc their CSOs. :3
