[tmp] Revert back to installing pygolang from PyPI

With setuptools==67.8.0, pygolang does not install properly from
git clone for some reason. The issue seems to be that some DSOs
are not copied from build directory to target directory, such as
liblibgolang.so. They then fail to resolve at runtime.

With setuptools==44.1.1 it works.
