util/cbfstool: add machine parseable print
In order to more easily process the output of 'cbfstool print'
with other tools provide a -k option which spits out the
tab-separated header and fields:
Name Offset Type Metadata Size Data Size Total Size
ALIGN_UP(Offset + Total Size, 64) would be the start
of the next entry. Also, one can analzye the overhead
and offsets of each file more easily.
Example output (note: tabs aren't in here):
$ ./coreboot-builds/sharedutils/cbfstool/cbfstool test.serial.bin print
-r FW_MAIN_A -k
Performing operation on 'FW_MAIN_A' region...
