xcb: reduce focus-in delay
This patch amends fe63900dc9891dd355ca1f10d6c7e5fd1516f5d5
The previous value of 400ms was a random and seemingly harmless choice.
It turns out that 400ms is a bit too long and interferes with x11 async
behavior tweaks in the VirtualBox source code.
The original aim of specifying a concrete delay was to fix the
nondeterministic behavior of the pre-existing code and to avoid flickering
on KWin caused by waiting too little. This patch changes 400ms -> 100ms,
which seems to work better in practice.
Fixes: QTBUG-76742
