Joe Lawrence 2f3f651f37 selftests/livepatch: Use "comm" instead of "diff" for dmesg
BusyBox diff doesn't support the GNU diff '--LTYPE-line-format' options
that were used in the selftests to filter older kernel log messages from
dmesg output.

Use "comm" which is more available in smaller boot environments.
