Rename weston_compositor_xkb_init to weston_compositor_set_xkb_rule_names

weston_compositor_xkb_destroy() is called automatically so having only
weston_compositor_xkb_init() to be called by the user was a bit weird.
So rename it so that it makes more sense.
Also export it, since libweston compositors need to call it.
