Correct some missing endian conversions of IPv4 addresses
The INADDR_LOOPBACK constant is in host endianness, and similarly the
IN_MULTICAST macro expects a host endian address. However, there are some
places in passt where we use those with network endian values. This means
that passt will incorrectly allow you to set 127.0.0.1 or a multicast
address as the guest address or DNS forwarding address. Add the necessary
conversions to correct this.
INADDR_ANY and INADDR_BROADCAST logically behave the same way, although
because they're palindromes it doesn't have an effect in practice. Change
them to be logically correct while we're there, though.
