openvpn: T2550: fix for IPv4 remote-host addresses
Commit bb9f998 added IPv6 support for OpenVPN, but IPv4 only configurations stopped working (Address family for hostname not supported) Commit fc467519 fixed some scenarios by using IPv4 protocols if 'local-host' is IPv4 address, but the client mode is using 'remote-host' instead and was still broken. This commit in addition to 'local-host' also checks all the 'remote-host' addresses.
