Thanks for your research!  As you note, the right way to fix this is
to fix send_rpc_query() to handle IPv6 addresses.  It shouldn't be too
hard, since it isn't generating raw packets and Nmap already has the
code to handle TCP and UDP communication over IPv6.  Anyone want to
give it a try?  We support IPv6 for the rest of version detection, so
we should do so for RPC scan, unless there is some major difficulty
with doing so.
