We have to disable the GLSL unit tests because with asan it runs way too
much code under qemu and times out. Those unit tests have coverage on
x86, anyway.
I also included a vulkan run, which is disabled by default due to timeouts
that I need to sort out still. It should be a useful tool for turnip
devs, though.
