Yesterday we merged https://review.opendev.org/#/c/707062 -> [install-deps]Install "virtualenv<20.0.1" which removes the previously installed virtualenv from rpm as well as pip
Since IN RHEL-8, we have only rpm it will work fine.

We need to tweak the workaround for not removing python-virtualenv in RHEL-8 will fix the issue.

    Donot remove virtualenv for RHEL-8

    Since RHEL-8 virtualenv rpm works fine and is not incompatible.
    Removing venv there breaks the whole RHEL8 jobs. So keep the
    workaround for CentOS 7 only.

    For CentOS-8, we will be using Python3 so it will not affect.
