[PATCH] update.sh: Core 194 - increment ipsec serial file if x509 set exists

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

- This is related to the fix patch set for bug13737. That patch set works with no problems
   if the root/host x509 set is created for the first time with that patch set merged.
   However if the x509 is already created previously then the contents of serial will
   still be 01 instead of 02.
- This patch checks if the hostcert.pm file exists and that the index.txt file is empty,
   and then increments the serial content from 01 to 02. This means that when the x509
   is regenerated the system will not complain that 01 cannot be used as it has already
   been revoked but will use 02 for the new host and everything works fine after that.
