factory_install: Allow debug console if cros_debug is defined.
When installation failed, we do want a friendly environment to help debugging.
Since kernel is always signed, a cros_debug ensures that the system was not boot
as official signed images.
To enable the flag:
- netboot: Override command line by files on TFTP.
- factory install shim: Add cros_debug into --boot_args.
BUG=none
TEST=build_image factory_install --boot_args "noinitrd cros_debug"
