media assets: fix .webm files not including video/audio bit rates in metadata.
...
Fix .webm files not including the `FFmpeg:VideoBitRate` and `FFmpeg:AudioBitRate`
fields in the media_metadata table. This was because the .webm format
doesn't include the video or audio bit rates in the metadata, and
ffprobe doesn't calculate them either, so we have to calculate them
ourselves by hand.

uploads: fix it being possible to upload .mkv files as .webm.
...
Fix it being possible to upload arbitrary .mkv files and have them
be treated as .webm. This was possible because WebM uses the Matroska
container format, and we only checked for the Matroska header, not that
the file was actually a WebM.
There were only 6 such files in production:

These videos are playable in Chrome, but not in Firefox, since Firefox
doesn't support .mkv files (it supports some, depending on which codecs
are used, but not .mkv files in general).
