  Bug #32063 "create table like" works case-significant only in "embedded" server
(libmysqld)
  
  in mysql_creata_like_table() we 'downcase' the complete path to the
  .frm file. It works fine in standalone case as there usually
  we only have './' as a path to the datahome, but doesn't work in
  the embedded server where we add the real path there, so if a
  directory has uppercase letters in it's name, it won't be found.
  
  Fixed by 'downcasing' only database/table pair.
