Prerequirement is as follow:
1. This test should run in Dev mode.
2. Enable dev_boot_usb and dev_boot_signed_only.
3. A USB disk should be plugged-in, which contains a Chrome OS Test Image.

This test will fail if one of the following conditions is met:
1. Ctrl-U boots to USB image with recovery keys.
2. Enabling rec mode, if it doesnt boot to USB image.
3. Ctrl-U doesnt boot to USB image after it resigned with SSD keys.

This test requires a USB disk plugged-in, which contains a Chrome OS test

DUT to developer mode. When dev_boot_signed_only=1 and dev_boot_usb=1 and,
pressing Ctrl-U on developer screen should not boot the USB disk. On resigning
