[grilo-plugins] tracker: Relax tracker version requirement

[Juan A. Suarez Romero <jasuarez src gnome org>]

commit 48e7dd1dfefef29d1cc56d18725a0b71a69dedc1
Author: Juan A. Suarez Romero <jasuarez igalia com>

    tracker: Relax tracker version requirement
    
    Tracker 0.10.5 defines nfo:lastPlayedPosition.
    
    But we can live with older versions if we ignore that key.
    
    So let's use it only if we have such Tracker version.
