Subject: [PATCH] Refocus focused window for focus in events on the root
 window. (#3543)

This deals with (admittedly somewhat misbehaving) clients which
use XSetInputFocus to take focus, but then don't properly restore
focus. This has been observed with TK apps, but also, e.g., Steam.

Ported from https://github.com/i3/i3/commit/a06e66982bc921d05b68b75f8e12323c284233d0 by @psychon

Fixes https://github.com/awesomeWM/awesome/issues/3379
