When opening an output file, use "file_snaplen" as the snapshot length, 

rather than "pcap_snapshot(ld.pch)" - we've set "file_snaplen" to
"pcap_snapshot(ld.pch)" if we're capturing from a device, but if we're
reading from a pipe, "ld.pch" is null (so we'll crash if we use it), and
we've set "file_snaplen" from the header we've read from a pipe.
