[mod] aol engines: disable by default (#5975)

The AOL engines deliver no results or too many incorrect results; in #5972 it is
reported that the AOL-images do not work, and on AOL-web the language selection
seems to depend more on the IP than on the selected language / Locally, the
language selection works for me, on the public server only English results are
displayed, which significantly worsens the result list.
