Linux (bzImage) payloads used to be totally not compressed with
cbfstool. However, only bzImage is already compressed and initrd is
usually compressed, but the trampoline, parameter, and kernel command
line should be compressible.
Now cbfstool can copy segments instead when compression fails, so
compression for Linux payloads (including LinuxBoot) could be enabled
for compressible components.
TEST=With LZMA, parameter is compressed from 0x1000 to 0x4c,
trampoline is compressed from 0x171 to 0x14b, kernel command line
is not compressed for being too short (0x22), initrd is not
compressed for being already compressed.
