Reviewed by Eric Carlson.

Recent changes in the AVFoundation framework have caused canPlayType() queries for
`application/vnd.apple.mpegurl; codecs="stpp.ttml.im1t"` and
`application/vnd.apple.mpegurl; codecs="wvtt"` to fail. These were never well-formed
queries in the first place, as `application/vnd.apple.mpegurl` does not take a codecs
parameter. However, Hulu.com appears to depend upon those queries returning "probably"
in order to vend a working HLS stream.

Add a quirk for hulu.com only which hard codes the answer to those two canPlayType()
queries to "probably".
