+    tests: ignore stderr from openssl
+    
+    Without this patch, the test failed with openssl-1.0.2p
+    because 502 lines were captured with the extra lines being at the end:
+    140510355240592:error:02012020:system library:fflush:Broken pipe:bss_file.c:434:fflush()
+    140510355240592:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:436:
+    
+    neither openssl-1.0.2j nor 1.1.0h needed this patch.
