[gnome-shell] shell-recorder: Make drawing the cursor optional

[Florian Müllner <fmuellner src gnome org>]

commit dc3082e66d31250094527c18a0b97d14e4ac1b00
Author: Florian Müllner <fmuellner gnome org>

    shell-recorder: Make drawing the cursor optional
    
    As with screenshots, showing the cursor in a recording may not be
    desirable, so add a property to control whether the cursor is drawn
    or not.
