Bug 13785: koha-disable should also stop SIP and zebra for instance

Currently koha-disable ONLY disables the instance in the apache conf
file. Presumably if you want to disable the instance, you also want
its processes to stop, so this patch will stop zebra, if running,
and SIP, if enabled.

Depends on Bug 13784.

To Test:
1) Have an enabled instance, with zebra and SIP running.
2) Run koha-disable INST. Note that after, both zebra and SIP
   will still be running.
3) Re-enable INST.
4) Apply patch, and then copy debian/scripts/koha-disable to
   package site, over /usr/sbin/koha-disable.
5) Run koha-disable INST. You should now see that both zebra
   and SIP have been stopped.
