Percona Server 5.5.30-30.2 rerelease fixes non-restart issue

In our last 5.5 series release of Percona Server, we included a regression in the RPM packaging that prevented the server from restarting following an upgrade — instead, the server would remain stopped after the upgrade was completed regardless of its state before updating.
