[sonic-utilitites-build] Do not install Python 3 version of sonic-py-…

…common for now (sonic-net#144)

sonic-py-common has other dependencies, so we also need to install Python 3 versions of those packages. Since we are not yet building a Python 3 version of sonic-utilities, I am temporarily omitting the installation of the Python 3 sonic-py-common package.
