[gtk-vnc] Disable deprecation warnings

[Daniel P. Berrange <dberrange src gnome org>]

commit b9e1ccfd83471cea0101047f2707cdb40cf40a9a
Author: Daniel P. Berrange <berrange redhat com>

    Disable deprecation warnings
    
    Glib deprecated GValueArray in favour of GArry
    
      gvncviewer.c:450:9: warning: âg_value_array_get_nthâ is deprecated (declared at /usr/include/glib-2.0/gobject/gvaluearray.h:65): Use 'g_array_index' instead [-Wdeprecated-declarations]
    
    Unfortunately these types are not ABI compatible. eg
    compare the field orders
    
      struct GValueArray {
        guint   n_values;
        GValue *values;
      };
    
    vs
    
      struct GArray {
        gchar *data;
        guint len;
      };
    
    So the replacement can't be used without a change in API
    and ABI. This is unacceptable, so the deprecation warniings
    must be disabled :-(
