[PATCH] Resolve PROTOREMOTEHOST or PROTOLOCALHOST when only one is specified

["George Matsumura via supervision" <supervision@list.skarnet.org>]

Previously, specification of PROTOLOCALHOST on the command line with the -l
option would lead to PROTOREMOTEHOST not being resolved. This did not seem to
be the intended behaviour, especially as the call to s6dns_resolven_parse_g
works with any combination of the state of previous hostname definitions. This
change alters the conditional to conduct the necessary resolutions in all
cases. I apologize if I misinterpreted or was mistaken about anything.
