ovsdb-server: Avoid intermittent test failures due to lockfile log message.

Sometimes lockfile will emit a message saying that it took a little while
to get the lock, which caused spurious test failures.  This commit
suppresses the message.  With this change, I was able to run these tests
continuously for some time without failures.

This was a bug in the testsuite, not in the code under test.
