wayland/keyboard: Check keyboard presence at set focus call site

Browse Source 
Make the caller of focus setting and grab starting check whether there
is a keyboard to update the focus state or start grabbing. It makes it
more obvious what to expect, as the call would be a no-op in when no
keyboard is present.
