[evolution] Rewrite champlain-gtk and geoclue detection.

[Matthew Barnes <mbarnes src gnome org>]

commit 447a71143fe9ced006da874853bc83aba2e246da
Author: Matthew Barnes <mbarnes redhat com>
Date:   Sat Nov 28 16:54:41 2009 -0500

    Rewrite champlain-gtk and geoclue detection.
    
    Disabling desktop integration features must be explicit.
    
    If experimental plugins are enabled and unless --disable-contacts-map is
    given, configuration will fail if champlain-gtk or geoclue is missing.
