[Devel] [PATCH vz10 2/4] selftests: net: py: add the missing ksft_is() and ksft_not_in() helpers

[Eva Kurchatova]

rss_api.py and rss_flow_label.py call ksft_is() and ksft_not_in(), and
net/lib/py/__init__.py exports both, but ksft.py never defined them, so
importing the library fails and every test of the group goes down with
it:

  ImportError: cannot import name 'ksft_is' from 'net.lib.py'

The tests and the export came in with the RHEL10 import, commit
9f055df11343 ("rh10: import RHEL10 kernel-6.12.0-211.16.1.el10"), the
helpers did not. Take them from the commits that added them upstream,
commit 31eae6d99587 ("selftests: drv-net: test drivers sleeping in
ndo_get_stats64") for ksft_is() and commit 4fde8398462f ("selftests:
drv-net: improve the use of ksft helpers in XSK queue test") for
ksft_not_in(). The tests those commits add are left out.
