Have L3 agent catch the correct exception

L3 agent imports the processutils module to catch exceptions that
wouldn't ever be thrown because the underlying execute() being
called is the one from neutron.agent.linux.utils which raises a
RuntimeError on failure.

Also, processutils is now part of oslo.concurrency. So when we
actually start using it, we'll use it from there.
