lib: changed Usb::Error exception to deal in libusb_errcode instead of system
No error information should ever be lost, and in the libusb translation
code, there was a slight possibility that it could be lost.
This commit makes sure that the Usb::Error exception always stores the
low level errcode, and adds a system_errcode() function to translate
it for error handling purposes, such as for common errors like -EBUSY.
