Kristof Provost 80c2f5fc0a if_pflog: fix packet length 
There were two issues with the new pflog packet length.
The first is that the length is expected to be a multiple of
sizeof(long), but we'd assumed it had to be a multiple of
sizeof(uint32_t).

The second is that there's some broken software out there (such as
Wireshark) that makes incorrect assumptions about the amount of padding.
That is, Wireshark assumes there's always three bytes of padding, rather
than however much is needed to get to a multiple of sizeof(long).

Fix this by adding extra padding, and a fake field to maintain
Wireshark's assumption.
