Keep the default AuthorizedKeysFile setting. Although authorized_keys2

has been deprecated for a while, some people still use it and were
unpleasantly surprised by this change.

I may revert this commit at a later date if I can come up with a way
to give users who still have authorized_keys2 files sufficient advance
warning.
