[PATCH 4/6 v2] backup.pl: Fixes bug13737 - restarts ipsec to use the restored certs etc

[Adolf Belka <adolf.belka@ipfire.org>]

- This adds a check if the ipsec server is enabled. If it is then ipsecctrl is run to
   restart ipsec and ensure that the restored certs are all being used.
- Tested this out on my vm testbed and confirmed that with this I could restore a backup
   and make the client connection as previously set up.
- Without this I had to press the Save button on the ipsec WUI page to get the certs
   etc being used.
