Patrick Georgi 12631a4d1d util/cbfstool: Add "truncate" command ...

It does the opposite to "expand", removing a trailing empty file from
CBFS. It also returns the size of the CBFS post processing on stdout.

BUG=b:65853903
BRANCH=none
TEST=`cbfstool test.bin truncate -r FW_MAIN_A` removes the trailing
empty file in FW_MAIN_A. Without a trailing empty file, the region is
left alone (tested using COREBOOT which comes with a master header
pointer).
