Marton Balint 2dbe936bf7 avformat/webm_chunk: always use a static buffer for get_chunk_filename 
My conversation from AVFormatContext->filename to AVFormatContext->url was
wrong in this case because get_chunk_filename uses filename as an output
buffer, and not as an input buffer.

Fixes ticket #7188.
