Reviewed by Jean-Yves Avenard.

When loading through blob, WebCoreAVFResourceLoader is used.
`application/ogg` mime type does not lead to a valid UTI and AV player is not 
able to recover itself.

Mime Sniffer is used but it will still return `application/ogg`.
We update MediaPlayerPrivateAVFoundationObjC::createAVAssetForURL to use 
`audio/ogg` in case `application/ogg` is the preferred mime type.
We only do this for blob URLs and should follow-up for all URLs.
We skip the test on iOS due to the lack of ogg support there.
