pimd: Fix register message checksum
The register message checksum was being calculated over
the first 4 bytes of the packet, instead of the first
8 bytes. From the RFC:
PIM Version, Type, Reserved, Checksum
Described in Section 4.9. Note that in order to reduce
encapsulation overhead, the checksum for Registers is done only
on the first 8 bytes of the packet, including the PIM header and
the next 4 bytes, excluding the data packet portion. For
interoperability reasons, a message carrying a checksum
calculated over the entire PIM Register message should also be
accepted. When calculating the checksum, the IPv6 pseudoheader
"Upper-Layer Packet Length" is set to 8.
