[PATCH] selftests: net: rds: fix module not found

[Alessandro Zanni]

This fix solves this error, when calling kselftest with targets "net/rds":

selftests: net/rds: test.py
Traceback (most recent call last):
  File "tools/testing/selftests/net/rds/./test.py", line 17, in <module>
    from lib.py import ip
ModuleNotFoundError: No module named 'lib'

Does this work regardless of where we try to run the script from?
In other cross-imports we try to build the path based on __file__,
see: tools/testing/selftests/drivers/net/lib/py/__init__.py

Would be good to keep consistency.

Yes, it works regardeless where we run the script from but I agree
with you to keep the same style used in other files.
Thanks for pointing out.

Definitely. I'm sending a v2 patch with this in mind.
