ftdi: make ftdi_location command depend on libusb1 version

The function libusb_get_port_numbers(), required for the command
ftdi_location, is only available in recent version of libusb1.
Compilation will break if the function is not available. This patch
enables the command only if libusb1 contains the necessary function.
