ipatests: azure: Use distro's setuptools

setuptools 60+ switched to bundled version of distutils
(stdlib's one will be removed in the future):
pypa/setuptools#2143
pypa/packaging-problems#127

ALT patches stdlib's version of distutils but not the setuptools's
one yet. For example, if the system's setuptools replace distutils
with its bundled one but the virtualenv's setuptools (bundled wheel)
doesn't do it (for example, setuptools < 60), then the behaviour
will be inconsistent:
```
[builder@localhost freeipa-4.9.8]$ python3 -c "import distutils.sysconfig;print(distutils.sysconfig.get_python_lib(prefix='/usr'))"
/usr/lib/python3.9/site-packages
```

```
[builder@localhost freeipa-4.9.8]$ export SETUPTOOLS_USE_DISTUTILS=stdlib
[builder@localhost freeipa-4.9.8]$ python3 -c "import distutils.sysconfig;print(distutils.sysconfig.get_python_lib(prefix='/usr'))"
/usr/lib/python3/site-packages
```

This happens in FreeIPA CI:
