test-runner: start dmesg early with --follow

Browse Source 
dmesg was being called at the very end of testing and dumped into
a log file. If many tests were run this could take quite a long
time and was timing out the default process wait. Instead --follow
can be used (basically like 'tail') which prints messages as they
come and avoids the time consuming full dump at the end.
