Subject: - move usb devices proc entry path into  
 libldetect-private.h::proc_usb_path

- add -u option so that lspcidrake can read usb devices from a file in
  order to understand what happened to remote testers

- make if (test) action clearer by rejecting action singleton in next
  line

- lspcidrake: describe all options
