Patrick Georgi c88d16baaf util/cbfstool: Add cbfs-compression-tool 
cbfs-compression-tool provides a way to benchmark the compression
algorithms as used by cbfstool (and coreboot) and allows to
pre-compress data for later consumption by cbfstool (once it supports
the format).

For an impression, the benchmark's results on my machine:

measuring 'none'
compressing 10485760 bytes to 10485760 took 0 seconds
measuring 'LZMA'
compressing 10485760 bytes to 1736 took 2 seconds
measuring 'LZ4'
compressing 10485760 bytes to 41880 took 0 seconds

And a possible use for external compression, parallel and non-parallel
(60MB in 53 files compressed to 650KB on a machine with 40 threads):

$ time (ls -1 *.* |xargs -n 1 -P $(nproc) -I '{}' cbfs-compression-tool compress '{}' out/'{}' LZMA)

real	0m0.786s
user	0m11.440s
sys	0m0.044s

$ time (ls -1 *.* |xargs -n 1 -P 1 -I '{}' cbfs-compression-tool compress '{}' out/'{}' LZMA)

real	0m10.444s
user	0m10.280s
sys	0m0.064s
