faft: Directly run usbkm232-xxx commands on devices without build-in keyboards
For the device without build-in keyboards, we use an additional USBKM232
device, which is connected between servo board and DUT, to emulate an
external USB keyboard. The key-sending commands are ready, like usbkm232-enter,
usbkm232-ctrld, etc. So far we pass this commands to FAFT via arguments
manually. However, an user may forget to pass these arguments to the test
and cause a test error.
This CL is to run the commands directly without configuring them. A simple
check is added to ensure the environment variable USBKM232_UART_DEVICE is
set correctly.
