keybindings: Do not grab the locate-pointer key if unnecessary

Browse Source 
On X11, mutter needs to keep a grab on the locate-pointer key to be able
to trigger the functionality time the corresponding key combo is
pressed.

However, doing so may have side effects on other X11 clients that would
want to have a grab on the same key.

Make sure we only actually grab the key combo for "locate-pointer" only
when the feature is actually enabled, so that having the locate pointer
feature turned off (the default) would not cause side effects on other
X11 clients that might want to use the same key for their own use.
