Add -b and -s flags for adding YP_INTERDOMAIN and YP_SECURE entries to

map databases. Also document said flags in the man page.

Adding YP_INTERDOMAIN to a map causes ypserv(8) to do a DNS lookup
when a yp_match() on the map fails. (This affects only the hosts.by*
maps; for all other maps it's ignored.) The YP_SECURE entry causes
ypserv(8) to restrict access to the map so that only clients making
requests from reserved ports can get at it.

Our ypserv doesn't currently support these features so they're silently
ignored for the moment, but this will change. :)
