[IPV6]: Add ip6_local_out
Most callers of the LOCAL_OUT chain will set the IP packet length
before doing so. They also share the same output function dst_output.
This patch creates a new function called ip6_local_out which does all
of that and converts the appropriate users over to it.
Apart from removing duplicate code, it will also help in merging the
IPsec output path.
