Subject: [PATCH] Run prelock and postlock synchronously to avoid race
 condition

As reported in issue #285, running postlock in a subshell and immediately
returning from lockselect() has a high chance of hitting `exit 0` before
xset and dunstctl get a chance to execute.

Run both prelock and postlock synchronously within lockselect().
