Christian Kellner 9a40cbc99a spec: require matching python3-osbuild version
The `osbuild` executable requires that the exact same version of the
corresponding python library is installed, but this was not enforced
in the RPM package. Thus a old version of osbuild could be installed
alongside an older version of python3-osbuild, which results in an
osbuild crash (see below).
Therefore, enforce that both installed packages have matching
versions by specifying the exact version for the `python3-osbuild`
dependency of the `osbuild` package.

Example osbuild crash if versions are not matching:

Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 583, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 900, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3.8/site-packages/pkg_resources/__init__.py", line 791, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (osbuild 10 (/usr/lib/python3.8/site-packages), Requirement.parse('osbuild==11'))

During handling of the above exception, another exception occurred:
