Bug 10624: add 'status' option switch for the packages init script

This patch makes the init script return the status of the relevant
processes.

To test:
- Apply the patch, build package and install
- Run
 $ service koha-common status

Note: it can be tested just copying the debian/koha-common.init script
to a server running koha-common instances and calling it

 $ ./koha-common.init status
