[ovs-dev] [warnings 8/8] tests: Check ovs-openflowd log output instead of ignoring it.

[Ben Pfaff]

ovs-openflowd outputs a number of log messages that we don't want to
suppress.  We do want to know if it logs anything that we don't expect.
So this commit starts checking the log output, discarding any normal,
expected messages.
