Subject: [PATCH] MediaWiki: remove the obsolete "fix audio" replacement

I have searched for the "<button" string and even for the "<\s*button"
pattern in tens of articles from all 5 default Wikipedia and all 5
default Wiktionary sites. Found none. I assume this pattern is obsolete.
Removing this useless code improves performance by doing less searching.

I have run the following command on directories that contained many
Wikipedia and Wiktionary articles received by GoldenDict:
  pcregrep -MrI --buffer-size 20M '<\s*button' DIR-WITH-ARTICLES
