[OE-core] [poky][PATCH v5 1/3] gstreamer1.0-plugins-base: Add gststreamsynchronizer related patch

[Yuqing Zhu]

-Sending EOS event instead of GAP event as GAP event has error if A/V have the different duration.

-Stop sending second track EOS event when returing failure after sending the first track EOS.
 Fixed by ignoring the return error.

+[streamsynchronizer] One stream can finish playback.
+  
+As changed GAP event EOS event, so EOS will send more times, which will
+cause send function return error.
+Streamsynchronizer will don’t send second track EOS event if send the
+first track EOS return fail. Fixed by ignore the return error.
