Description of problem:
python3-libs has a hard requirement on python3

This is a regression mos likely caused by the new in the python(abi) dependency generator.

Version-Release number of selected component:
3.9.0~b5-2.fc33


Steps to Reproduce:
1. $ mock -r fedora-rawhide-x86_64 --enablerepo=local --install python3-libs
2. $ mock -r fedora-32-x86_64      --enablerepo=local --install python3-libs

Actual results:
1. Installs python3-libs and python3 is pulled as a dependency
2. Installs python3-libs without python3

Expected results:
1. Installs python3-libs without python3
2. Installs python3-libs without python3


Additional info:

Fedora 33:

<mock-chroot> sh-5.0# rpm -q --requires python3-libs | grep python
libpython3.9.so.1.0()(64bit)
python(abi) = 3.9
python-pip-wheel
python-setuptools-wheel

Fedora 32:

<mock-chroot> sh-5.0# rpm -q --requires python3-libs | grep python
libpython3.8.so.1.0()(64bit)
