run-tests: drop a workaround for python2

The problem is only on python3, but the awkward handling was because python2
didn't have this exception type.  I've sporadically seen it running in WSL, but
no clue what it means.

        #       works because socket.error is an alias for OSError on py3,
        #       which is also the baseclass of PermissionError.
