rumpnet: Fix BPF record alignment on amd64 Hurd systems

[Michael Beecher via Bug reports for the GNU Hurd]

Hi all,

Patch attached. I found this while getting networking usable on hurd-amd64 on 
my Dell E6420 (82579LM). I noticed TCP was very slow and saw that bursts of 
packets got dropped consistently.

Thanks, Michael.
