Add support for flags in the firmware preamble.
The old (v2.0) parser is compatible with new (v2.1) structs. That is,
this won't break existing firmware or vbutil_firmware.
A new (v2.1) parser parsing an old (v2.0) struct will return 0 for the
flags.
This will be used to support the RO-normal code path in a subsequent CL.
