net/isc-dchp41-server port installs two RC_SUBR scripts: isc-dhcpd and

isc-dhcpd6 when it is built with IPv6 support.  net/isc-dchp41-relay could be
built with IPv6 support, but it doesn't provide way to start two realys (for
IPv4 and IPv6) simultaneously.  This patch changes RC_SUBR script isc-dhcrelay
to support such operations, and install link from isc-dhcrelay to isc-dhcrelay6
when port is built with IPv6 support.
