Fix the broken sys import of distutils

Newer distutils versions allow to list and work with `sys` as it is
imported in the `__init__.py` however, the older versions of disutils
does not contain anything other than the version and revision strings.
The current installation procedure relied on the former method which is
only adapted in the new versions so make it compatible to the older
versions by importing `sys` from `distutils.core`.

Closes redmine ticket #2747
