At least two places in passt calculate ICMPv6 checksums, ndp() and
tap_ip_send(). Add a helper to handle this calculation in both places.
For future flexibility, the new helper takes parameters for the fields in
the IPv6 pseudo-header, so an IPv6 header or pseudo-header doesn't need to
be explicitly constructed. It also allows the ICMPv6 header and payload to
be in separate buffers, although we don't use this yet.
