From: Florian Westphal <fw@xxxxxxxxx>
[ Upstream commit c21b02fd9cbf15aed6e32c89e0fd70070281e3d1 ]
These scripts fail if the kernel is tainted which leads to wrong test
failure reports in CI environments when an unrelated test triggers some
splat.
Check taint state at start of script and SKIP if its already dodgy.
