gitlab-ci: Run piglit glslparser & quick_shader tests separately

And only use --process-isolation false for the quick_gl tests.

This will hopefully avoid variance in the test results that we've been
seeing lately. But even if it doesn't, it should at least help narrow
down the cause of the variance.
