staging: usbip: userspace: show product name in `list -l' command

The `usbip list -l' command shows your local usb-devices.
Example:
 $ usbip list -l
 $ Local USB devices
 $ =================
 $ - busid 1-1 (13fe:1d00)
 $         1-1:1.0 -> usb-storage
 $
 $ - busid 1-2 (0409:55aa)
 $         1-2:1.0 -> hub

However this list command doesn't show which device is connected
to this busid. Therefore you have to use another tool e.g. lsusb
to determine that.

This patches adds the possibility to see which device that is.
Example:
 $ usbip list -l
 $ Local USB devices
 $ =================
 $ - busid 1-1 (13fe:1d00)
 $   Kingston Technology Company Inc. : DataTraveler 2.0 1GB/4GB Flash Drive / Patriot Xporter 4GB Flash
 $         1-1:1.0 -> usb-storage
 $
 $ - busid 1-2 (0409:55aa)
 $   NEC Corp. : Hub (0409:55aa)
 $         1-2:1.0 -> hub

If parsable is specified the info will be not printed.
