Reintroduce the possibility to hexdump(3) PCD <=> PICC transmissions.

Browse source 
Not a hack this time:
  - Use the hexdump(3) function of the system if it exists;
  - Build the subpart of FreeBSD's libutil if not (contrib);
  - Do this only if configured --with-debug.

The Mifare Classic / Ultralight code will be eventually changed to also provide this functionality.
