[PATCH iptables] fix wrong headername in ipv6header for protocols

[Andreas Herz <andi@geekosphere.org>]

In the --help output and manpage for ipv6header the name for upper layer
protocol headers was "proto", while in the code itself it's "prot" for
the short form. Fixed by changing manpage and help output.
