[evolution-data-server] Make GTK+ a soft dependancy

[Tristan Van Berkom <tvb src gnome org>]

    Make GTK+ a soft dependancy
    
    This patch disables building of the user-prompter service and trust-prompt
    module if GTK+ is not available, allowing alternative implementations of
    the user prompter service to be installed on platforms where GTK+ is not
    available.
