chromeos-boot-alert has an ability to re-enable verified mode.
Therefore, we should patch chromeos-boot-alert.
I've brought some code (deprovision) from SH1mmer to implement auto-repair in chromeos-boot-alert.
By patching chromeos-boot-alert, ChromeOS can boot even if chromeos_startup detected block_devmode.

This pull request also includes a commit to ask the user whether they need to update pollen.

This may be a solution for #72, #98, #133 and #136

tested successfully just now (on R130)

  1. do vpd -i RW_VPD -s block_devmode=1
  2. reboot immediately by performing EC-Reset.
  3. murkmod will bring back block_devmode to 0
  4. murkmod will boot ChromeOS directly.

It also seems the chromeos_startup binary checks both vpd and crossystem.
murkmod's chromeos_startup patch disables only crossystem one.
So, maybe we should patch chromeos_startup to disable vpd one for next.

I've already tested it and it has backward compatibility.
