cbfstool/extract: ignore compression field for some payload segments
When extracting a payload from CBFS, ignore compression fields for these types of payload segments: - PAYLOAD_SEGMENT_ENTRY - PAYLOAD_SEGMENT_BSS - PAYLOAD_SEGMENT_PARAMS These types of payload segments cannot be compressed, and in certain cases are being erroneously labeled as compressed, causing errors when extracting the payload. For an example of this problem, see creation of PAYLOAD_SEGMENT_ENTRY segments in cbfs-mkpayload.c, where the only field that is written to is |load_addr|. Also, add a linebreak to an ERROR line.
