libpayload: cbfs: Require input size and output size for cbfs_decompress
Currently, cbfs_decompress() calls ulzma() and ulz4f() for LZMA/LZ4
decompression. These two functions don't accept input/output size as
parameters. We can make cbfs_decompress more robust by calling ulzman()
and ulz4fn() instead. This could prevent us from overflowing destination
buffer.
BUG=none
BRANCH=none
TEST=boot into kernel on Kukui with COMPRESSED_PAYLOAD_LZMA /
COMPRESSED_PAYLOAD_LZ4.
