Take an environment variable, SELFTESTS=foo,bar, and pass that along to
the kernel (as i915.st_filter=foo,bar) to provide fine grained test
selection. This can be either as an exact match to select only that
test, or to exclude only test. For example,
SELFTESTS=igt_vma_create,igt_vma_pin1 i915_selftest --run mock_vma
SELFTESTS=!igt_vma_create i915_selftest --run mock_vma
