Patch

Stagefright uses libwebm to demux matroska files, but the library has a nasty
bug where it fails to parse tags/tag element without any contents; 

This has been fixed recently
https://bugs.chromium.org/p/webm/issues/detail?id=1125

but all Android version up to and include 6.0.1 are affected. There is good
chance that majority of devices will never get the fix. 

So while there is nothing wrong with the muxer, to ensure compatibility with
those devices attached patch makes sure that empty tags/tag elements are not
written.
