Re-enabled Xnest fix for focus in + modifier bug. 

* See https://bugs.freedesktop.org/show_bug.cgi?id=3030

Signed-off-by: Xiaoyang Yu (Max) <max.a.yu@intel.com>
Reviewed-by: Mikhail Gusarov <dottedmag@dottedmag.net>

This takes the xnest way of working around this (see
5904ef2ccd "xnest: restore
xnestUpdateModifierState") and copies it to Xephyr.
