fixing install error info: struct.error: argument for 's' must be a bytes object
Because mic package is py3 version, During apt-get install mic, after mic is installed,
it will call py3compile binary to build *.py file, but the python file in mic_py2 directory
is py2, it will have show error info.
Now we use compress them to a tar.gz, then decompress it to /usr/lib/mic in post install step.
