Fix option inconsistency warnings about "proto" and "tun-ipv6"
"tun-ipv6" is only sent in option string if running in point-to-point
mode (= not --server and not --client or --pull), because in those
scenarios it's usually pushed by the server, and the client does not
yet have it when comparing options -> needless warning.
Completely ignore "proto" values when comparing option strings - this
is in preparation for removing proto from the option string in a future
release, and to avoid warnings when 2.3 talks to this future release.
