Sync dh-python 4.20201102+nmu1 (universe) from Debian unstable (main)

Please sync dh-python 4.20201102+nmu1 (universe) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
  * Disable the nosetests autopkg test. Unmaintained.
  * Disable the nosetests autopkg test. Unmaintained.
  * Fix DocTest.
-> Those have been fixed by the NMU

  * Don't run test t301.

-> I don't really understand the rationale for disabling this test.
While the test case specifies a python version << 3.9 which wouldn't make
it fit for current versions of Ubuntu, I believe what is being tested is the
ability to specify the version bounds properly, which shouldn't be affected by
the default version on the system.

Changelog entries since current impish version 4.20201102ubuntu4:

dh-python (4.20201102+nmu1) unstable; urgency=medium

  * Non-maintainer upload
  * Don't fail tests just because the default python gets hardcoded
    (Closes: #975536)
