Hello,

we observe a failure in RPM job executed as part of Component CI for OSP 18

```
oslo_rootwrap.tests.test_rootwrap.RootwrapTestCase.test_KillFilter
------------------------------------------------------------------

Captured traceback:
~~~~~~~~~~~~~~~~~~~
Traceback (most recent call last):

File "/home/zuul/src/code.engineering.redhat.com/oslo.rootwrap/oslo_rootwrap/tests/test_rootwrap.py", line 211, in test_KillFilter
self.assertTrue(f.match(usercmd) or f2.match(usercmd))

File "/usr/lib64/python3.9/unittest/case.py", line 688, in assertTrue
raise self.failureException(msg)

AssertionError: False is not true
```

What we do in the job, is:
– we fetch the spec file and install the RPM dependencies listed there,
– we install some missing RPMs identified (that should be in spec file probably, but they are not),
– we run the tests defined in tox.

The additional RPMs we install are listed here:

So, in essence, this is a tox job but with truncated requirement.txt and site-packages enabled.

You can use this change for debugging the issue.
