Fix issues that make these tests pass:
- TestDialerLocalAddr: return error if local address is not IPv4 for
"tcp4" network.
- TestInterfaceAddrs, TestInterfaceUnicastAddrs: don't assume each
interface has only one address. It may have more than one or none.
- TestConcurrentPreferGoResolversDial: should be skipped on Plan 9.
- TestListenMulticastUDP: remove IP from `announce` command and don't
mix IPv4 address with IPv6 address in `addmulti` command.
