Change dumpon(8)'s handling of -g.

Rather than using a special value to denote "use the default router",
treat the absence of the -g option to mean the same thing.  The
in-kernel netdump client will always attempt to reach the server
directly before falling back to the configured gateway anyway.  This
change makes it cleaner to support a hostname value for -g.
