clone: Fix error message for reference repository

Do not report that an argument to clone's --reference option is not a
local directory.  Nothing checks for the existence or type of the path
as supplied by the user; checks are only done for particular contents of
the supposed directory, so we have no way to know the status of the
supplied path.  Telling the user that a directory doesn't exist when
that isn't actually known may lead him or her on the wrong path to
finding the problem.

Instead just state that the entered path is not a local repository which
is really all that is known about it.  It could be more helpful to state
the actual paths which were checked, but I believe that giving a good
description of that would be too verbose for a simple error message and
would be too dependent on implementation details.
