runDialog: Disable restart command on wayland

Clients can be expected to deal with the WM going away temporarily,
but not the display server - so when running as wayland compositor,
a restart is generally a fancy way of killing the user session, and
there's little we can do about it except for preventing the user to
shoot herself in the foot by throwing an error.
