Strip out the current working directory from sys.path.

stdlib or pylint's own modules.
CPython issue: https://bugs.python.org/issue33053
- Remove the first entry. This will always be either "" or the working directory
- Remove the working directory from the second and third entries
if PYTHONPATH includes a ":" at the beginning or the end.
https://github.com/pylint-dev/pylint/issues/3636
Don't remove it if PYTHONPATH contains the cwd or '.' as the entry will
only be added once.
- Don't remove the working directory from the rest. It will be included
if pylint is installed in an editable configuration (as the last item).
