selftests/lkdtm: Don't clear dmesg when running tests
It is Very Rude to clear dmesg in test scripts. That's because the
script may be part of a larger test run, and clearing dmesg
potentially destroys the output of other tests.
We can avoid using dmesg -c by saving the content of dmesg before the
test, and then using diff to compare that to the dmesg afterward,
producing a log with just the added lines.
