Allow option (command line argument -e) to capture Ethernet headers
instead of IEEE 802.11 so that wlantest can be used as a replacement for
tcpdump/dumpcap for capturing.

This makes it easier to do live parsing of captured pcap files from
wlantest without having to rename and restart the capture file. Packet
writes are flushed to disk after each packet if -N is included in the
command line.

Rather than ignoring packets with a minimal 8-byte radiotap
header, which may occur elsewhere, tag generated (decrypted)
packets with an empty vendor namespace tag and ignore those.

When writing pcap-ng files, always include a radiotap
header even if there wasn't one in the input. For now
just drop prism headers, I don't have any to test.

The new -n<file> command line argument can be used to request wlantest
to write all read or captured frames into a pcapng file. This is similar
to the -w argument, but with pcapng allowing per-frame comments to be
embedded in the file.

The use of the pcap subdirectory seems to be limited to some of the
newer Linux distros only, so use the older paths to pcap.h and
pcap-bpf.h to make wlantest bit more easier to compile on older
systems.
The output file includes all the capture (or read from wireless PCAP
file) frames in their original contents and another copy of each
frame that is decrypted in wlantest (including EAPOL-Key Key Data
field).
