qtile: rework package

* Use absolute paths to load gobject, pango and cairo.
* Add xcb-cursor support (also with absolute path)
* Avoid tainting child processes environment:
  Save PATH and PYTHONPATH in wrapper, and restore them in python code.
* Alter restart process, using $0 saved in wrapper, which allow user
  to restart qtile after system rebuild to upgrade it.
