HBASE-29878 Monkey-patch YETUS-1266 fix for author_postcompile function

YETUS-1266 Escape regex metacharacters in author plugin ignore list

The author_postcompile function writes --author-ignore-list entries directly into a grep -E filter file without escaping. Filenames containing regex metacharacters (parentheses, brackets, etc.) are silently misinterpreted as pattern syntax, causing those files to pass through unfiltered.
