Description

Python 3.5 specific command scandir is being used when Python 3.4 is being used.
This cause an alert when starting QGIS, but also when closing the settings Dialog.

AttributeError: 'module' object has no attribute 'scandir'
Traceback (most recent call last):
  File ".... /apps_local/qgis_320.spatialite/share/qgis/python/plugins/processing/script/ScriptAlgorithmProvider.py", line 102, in loadAlgorithms
    items = os.scandir(folder)
AttributeError: 'module' object has no attribute 'scandir'

https://docs.python.org/3/library/os.html#os.scandir
New in version 3.5.

Python version: 3.4.6 (default, Oct 28 2017, 03:38:25) [GCC 4.9.1]

The external scandir for pre-3.5 was installed with:
python3 -m pip install scandir

Since only Python 3.0 is a requirement, version dependent code should offer an alternative since many non-Python users not not want to deal (yet again) with another Python error.
