The livepatch selftests currently filter out "tainting kernel with
TAINT_LIVEPATCH" messages which may be logged when loading livepatch

Further filter the log to drop "loading out-of-tree module taints
kernel" in the rare case the klp_test modules have been built
out-of-tree.

or make it just 'grep -v 'taint' ? It does not matter much though.
I don't know of any larger words* that may hit a partial match on
"taint", but I figured the two word bounded regexes would be more specific.
