This is #666651 again. The test suite launches a server on localhost,
and when the client connects with IPv6 it fails because RPC::XML doesn't
support IPv6 (it uses HTTP::Daemon which is IPv4-only, see #667738).

The patch that fixed this was dropped in 0.76-3 because it was "not
needed anymore with Net-Server 2.x". This seems to be incorrect. The
old problem with Net-Server was that it only bound to an IPv6 socket
(#667737), but that's fixed now and it binds with both IPv6 and IPv4. If
the client prefers IPv6 (as it usually does if there's a ::1 entry in
/etc/hosts), the test suite still breaks.

So the fix is simply to reinstate the patch from #666651.
