Rename the fix_unlocked_device_required_keys flag

This flag was defined as a regular flag and then was later changed to a
fixed_read_only flag.  This scenario is currently "unsupported" by the
flags infrastructure; an error occurs when trying to advance the flag to
staging.  Work around this by renaming the flag so that the flags
infrastructure sees it as an entirely new flag.
