python3-pytest: display correct version info

It does not show correct version info of python3-pytest:

$ pip3 list | grep pytest
pytest             0.0.0

pytest requires setuptools-scm in setup.cfg. It could be met by adding
python3-setuptools-scm-native to dependency and then it will not
download egg file of setuptools-scm during do_compile any more. So
remove 0001-setup.py-remove-the-setup_requires-for-setuptools-scm.patch
and depend on python3-setuptools-scm-native to make it show the correct
version info.

-Subject: [PATCH] setup.py: remove the setup_requires for setuptools-scm
-
-The setup_requires argument forces the download of the egg file for setuptools-scm
-during the do_compile phase.  This download is incompatible with the typical fetch
-and mirror structure.  The only usage of scm is the generation of the _version.py
-file and in the release tarball it is already correctly created
