on-the-fly testsuite: stablify

Remove the "-g" flag from both {k,u}probe tests; it's not needed, and
for the kernel case can trigger weird hangs due to overriding of the
blacklist.  Relax the output matching patterns, perhaps due to
different ordering of task workqueues in 4.3.0-rc.  Produce more
diagnostics upon failure.
