kpatch-test: clear dmesg just before tests commence 

Defer clearing the kernel buffer until we're ready to start the tests,
otherwise we increase the likelihood of catching stray errors while
we're building the modules and preparing the tests.

Fixes #1133 ("kpatch-test should ignore older kernel log messages")
