libavformat: fix spelling in ID3v1 genres and extend the list of Winamp extensions.

Sources include various lists on the Internet, as well as the current
Wikipedia page at
https://en.wikipedia.org/w/index.php?title=List_of_ID3v1_Genres&oldid=896774343
but most importantly the list as used by taglib at
3e60e339a4 (diff-f86455366624350770f41b4940925dde)

Further patches to harmonize the spelling have been sent to taglib and
libid3tag. See also https://github.com/taglib/taglib/pull/942/
