Upgrade glib to 2.51.1, needed for new glibcstaging/pedroalvarez/GENIVI-N0.1

Without this version, "ibus" was failing to compile with errors like:

    main.c: In function 'read_config':
    main.c:1431:5: warning: 'g_settings_list_keys' is deprecated: Use 'g_settings_schema_list_keys' instead [-Wdeprecated-declarations]
         _tmp8_ = _tmp7_ = g_settings_list_keys (_tmp6_);
