Servo based firmware update test, and check kernel subkey version.

CRITERIA = """
This test will fail if following requrements are met:
1. fwid does not match shellball's (/usr/sbin/chromeos-firmwareupdate) fwid
2. Kernel subkey version does not match original kernel subkey version.

This test requires firmware id matches fwid of shellball
chromeos-firmwareupdate. On runtime, this test modifies shellball and runs
autoupdate. Check kernel subkey version after boot with firmware B, and then
recover firmware A and B to original shellball.
