openfortivpn: version bump to 1.15.0 and further upgrades

Browse source 
- remove patch that has been included upstream
- remove dependence on resolveip
- remove hotplug script that is handled by "proto_add_host_dependency"
- use openfortivpn default tunnel ip if none specified
- add status checking with uclient-fetch
