Revert "x11: drop xscrnsaver use"

This broke screensaver/powersave inhibition with at least KDE and
LXDE. This is a release blocker.

Since fdo, KDE and GNOME idiots seem to be unable to reach
a consensus on a simple protocol, this seems unlikely to get
fixed upstream this year, so revert this change.

Fixes #4752.
Breaks #4706 but I don’t give a damn.

This reverts commit 3f75b3c3439241c209349908fa190c0382e44f05.
