Pipfile: Python requirements are the wrong way around

Unless I'm completely mistaken the Python version requirements for `scandir` and `typing` are the wrong way around in the `Pipfile`. Both modules/functions are part of Python >= 3.5, but the Pipfile *requires* them for Python **>** 3.5 (i.e. all versions that already include that functionality, except 3.5 itself), instead of Python **<** 3.5 (i.e. all versions that *need* this functionality in form of an extra module)

https://github.com/Guake/guake/blob/dcbf64c24e133b57d9023347bd17c13589ebb85f/Pipfile#L30
https://github.com/Guake/guake/blob/dcbf64c24e133b57d9023347bd17c13589ebb85f/Pipfile#L42

Both should be `"python_version < '3.5'"`

This even was the case before this commit: https://github.com/Guake/guake/commit/a38b47c97ca1161f82be9269fd7b4a418a6458da#diff-230078d672f10d17463a8a6265cad825b790885898256a3365be90685caac58d
