Make BIOS screens warn when GBB.flags is nonzero.


Until the factory flow has completed, BIOS screens should display a warning
message about GBB.flags. This message should disappear once the flags field
is zero.

You can see the state of the GBB flags in a particular BIOS image using

  gbb_utility -g --flags BIOS.bin

And set it with

  gbb_utility -s --flags=VALUE BIOS.bin NEWBIOS.bin
