Revert "Merge pull request #4854 from blueyed/pdb-skip"

This reverts commit e88aa957ae, reversing
changes made to 1410d3dc9a.

I do not think it warrants an option anymore, and there is a way to
achieve this via `--pdbcls` if needed.

-The ``--pdb-skip`` option can now be used to ignore calls to
-``pdb.set_trace()`` (and ``pytest.set_trace()``).
-
-This is meant to help while debugging, where you want to use e.g. ``--pdb`` or
-``--trace`` only, or just run the tests again without any interruption.
