selftests/livepatch: Don't clear dmesg when running tests
Inspired by commit f131d9edc29d ("selftests/lkdtm: Don't clear dmesg
when running tests"), keep a reference dmesg copy when beginning each
test. This way check_result() can compare against the initial copy
rather than relying upon an empty log.
