    SystemUI: VolumeDialogImpl: Move the MediaOutputDialog above status bar

    The volume dialog is above the status bar too and can be used while
    the statusbar is expanded. Opening the media output dialog then will
    cause the dialog to appear below the status bar which isn't visible
    until the status bar is collapsed. This change moves the media output
    dialog above the status bar.
