util/cbfstool: Fix truncate command error handling and cbfs_image_from_buffer()

Check return value of cbfs_truncate_space() in cbfs_truncate().
Remove return from cbfs_image_from_buffer() to inform about invalid
image region when incorrect offset header was provided.
Also change header offset provided to mentioned function in
cbfs_expand_to_region() and cbfs_truncate_space() from zero
to HEADER_OFFSET_UNKNOWN, as they do not support images with cbfs master
header.
