Workaround for unittests

Probably with the latest virtualenv [1] (which bundles setuptools), the
unit tests started to fail with this error:

  File "/home/zuul/src/opendev.org/openstack/requirements/.tox/py310/lib/python3.10/site-packages/pkg_resources/_vendor/packaging/requirements.py", line 37, in __init__
    raise InvalidRequirement(str(e)) from e
pkg_resources.extern.packaging.requirements.InvalidRequirement: Expected end or semicolon (after version specifier)
    lesscpy>=0.9h

It seems that the parser have become more strict and now it does not
accept other than 0.9a, 0.9b (alpha, beta) releases when parsing
constraints. This patch updates the global requirements test file to
not break the parser.

Also the test_match_without_python3_markers test caused the same error
(with: withmarker>=1.5') and needed an update.

[1] virtualenv (20.19.0) released at Tue, 07 Feb 2023 20:16:53 GMT
