A FAFT test case to check the developer firmware screen timeout.

When booting in developer mode, the firmware shows a screen to warn user
the disk image is not secured. If a user press Ctrl-D or a timeout reaches,
it will boot to developer mode. This test is to verify the timeout period.

This test tries to boot the system in developer mode twice.
The first one will repeatly press Ctrl-D on booting in order to reduce
the time on developer warning screen. The second one will do nothing and
wait the developer screen timeout. The time difference of these two boots
is close to the developer screen timeout.
