Fix locking mechanism for o365_mu and tinia services
Created by: stavamichal
- both services are using similar mechanism and they are trying to find running process with saved pid in the lock. If they not found such running process, they know that lock can be removed and created again. In other case they will end with error
- but we need to use "ps" with option "a" to see all running processes there or we can just miss the process we are looking for
