Subject: [PATCH] [wat] extract m3u8 formats instead of f4m formats(fixes
 #6678)

- sometimes f4m fragments are protected with Akamai Player Verification Token
https://github.com/rg3/youtube-dl/issues/6678#issuecomment-170147085
- sometimes they fail with 403 while the m3u8 formats works
- m3u8 manifest contain more formats
