Paolo Bonzini c03f57fd5b Revert "tests: Use separate virtual environment for avocado"

This reverts commit e8e4298fea.

ensuregroup allows to specify both the acceptable versions of avocado,
and a locked version to be used when avocado is not installed as a system
pacakge.  This lets us install avocado in pyvenv/ using "mkvenv.py" and
reuse the distro package on Fedora and CentOS Stream (the only distros
where it's available).

ensuregroup's usage of "(>=..., <=...)" constraints when evaluating
the distro package, and "==" constraints when installing it from PyPI,
makes it possible to avoid conflicts between the known-good version and
a package plugins included in the distro.

This is because package plugins have "==" constraints on the version
that is included in the distro, and, using "pip install avocado==88.1"
on a venv that includes system packages will result in an error:

   avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
   avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.

But at the same time, if the venv does not include a system distribution
of avocado then we can install a known-good version and stick to LTS
releases.

README

This directory contains scripts for generating a build of QEMU that
closely matches the CentOS Stream[1] builds of the qemu-kvm package.

To have the environment ready to configure, build QEMU and run tests,
please start with a CentOS Stream machine and:

 * apply the generic "build-environment.yml" playbook located at
   scripts/ci/setup

 * apply the "build-environment.yml" in the directory following the
   CentOS Stream version (such as "8").

This currently only covers CentOS Stream 8 environments and
packages[2].
