Ticket History #8348: Remove workaround when binding to udp addresses and pktinfo isn't supported by the system

Currently if the system doesn't support pktinfo and kadmind or krb5kdc
are binding to a upd address the system krb5 binds to all the local
addresses. Currently most systems support pktinfo, so the workaround
isn't really required anymore. Removing the workaround will only affect
systems that don't have pktinfo support and have multiple NICs and are
listening on a wildcard address. Users with this setup may specify each
of the local addresses directly that kadmind or krb5kdc should listen on
in kdc.conf.

Remove workaround when pktinfo is unsupported

Currently if the system doesn't support pktinfo and kadmind or
krb5kdc are binding to a UDP address, then the net server binds to
all the local addresses. Currently most systems support pktinfo,
so the workaround isn't really required anymore. Removing the
workaround will only affect systems that don't have pktinfo
support, have multiple NICs, and are listening on a wildcard
address.
