The livepatch selftests currently grep on "taints" to filter out "tainting kernel with TAINT_LIVEPATCH" messages which may be logged when loading livepatch modules.
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.
Look for the longer "taints kernel" or "tainting kernel" strings to avoid inadvertent partial matching.
