vboot: Add --programmer and --servo flags to {get,set}_gbb_flags.sh.
Allow custom programmers to be used instead of host for getting and
setting GBB flags via a --programmer/-p flag similar to the same flag
for futility. Also support --servo with the same semantics as the
futility flag - detecting the programmer to use from the current servod
instance mirroring the logic in futility. Only CCD is supported at this
stage.
When reading, include the FMAP section as well as the GBB section. For
writes over CCD, avoiding rescanning for the FMAP can save up to 1.8s.
BUG=None
TEST={get,set}_gbb_flags.sh --servo with and without servod running
BRANCH=None
