tools: Remove signalfd() use

Browse source 
Remove signalfd() use from the mouse-dpi-tool and touchpad-edge-detector
tools, in favor of using plain old signals.
FreeBSD does not have signalfd() without pulling in external libraries,
and with this change these tools can be compiled on FreeBSD.
Instead of providing two implementations, one using signalfd() and one
using signal(), just use the signal() implementation everywhere as it is
more portable.
