selftests: ovpn: validate peer VPN addresses

Browse source

Exercise peer VPN address validation through both peer creation and
update. Check missing, unspecified, duplicate, multicast, broadcast,
loopback, IPv4-compatible and IPv4-mapped addresses.

Temporarily configure a peer with both address families to verify that
either family can be cleared while the other remains configured, then
restore the original addresses before running the existing traffic
tests.

Extend ovpn-cli peer updates with an optional VPN address and preserve
peer creation errors so the negative tests can observe rejected netlink
requests.
