find_files(): don't sort files in my_dir(), sort table names

Browse source 
after all engines have discovered their tables
  
side effect: correct alphabetical sorting as in ORDER BY ... COLLATE utf8_bin,
information_schema is no longer the first after find_files(),
tables like #mysql50#zzz are sorted first (as per table name),
not last (as per file name zzz).
