    panels: Fix build with NetworkManager disabled
    
    Gentoo allows the user to disable NetworkManager integration at build time.
    We use the existing HAVE_NETWORK_MANAGER preprocessor macro to guard
    the uses of the mobile_switch_changed_cb and wifi_switch_changed_cb
    functions that guard their definitions.

    Closes: #1335
