Examining the ramdisk build recipe, I saw that bpf wasn't on the list
of device nodes to be created (though dhcpcd is included, and bpf is
enabled in the kernel configuration), so I've now added it.

I'm not able to test this directly, but verified by mounting the ramdisk
images generated before and after this change. Testing would be
appreciated.
