github-actions: Use constraints file instead of pre-installing packag…

…es on x86 (#2584)

Some python packages no longer provide x86 (32bit) wheels, and the CI
build environment is not good enough to build all of them from source.
Restrict versions of these packages in env_contraints.txt instead of
pre-installing the old versions.
