Don't use the power button to enter gluon setup mode.

Using the power button for setup mode would work for the AVM 3370, but
may side effects on other devices. On devices with a dedicated
controller for power management, 'power pressed' and 'power
released' events might be consumed by the controller, or emitted at
unexpected times. This might lead to shutdowns failing, the device
randomly put into setup mode, or similar things.

Support for an outdated, non-mainstream device such as the AVM 3370
shouldn't invite such extra problems.

Moreover, the feature in question can also be added after the
installation, simply by editing
`/etc/hotplug.d/button/50-gluon-setup-mode`
and changing one line:
`
-if [ "$BUTTON" = wps ] || [ "$BUTTON" = reset ] || [ "$BUTTON" = phone ]; then
+if [ "$BUTTON" = wps ] || [ "$BUTTON" = reset ] || [ "$BUTTON" = phone ] || [ "$BUTTON" = power ]; then
`
