cbfstool: show "preserved" flag in cbfstool layout output 

The flag is useful for updaters to determine which areas to leave
alone, such as VPD (vital product data) regions that are set in
factory and might contain unique (MAC addresses) or hard to obtain
(calibration output) data.

It's also useful to see which regions are marked as such.
