dev-db/freetds: new revision to add a missing REQUIRED_USE constraint.

The flags USE=iodbc and USE=odbc are actually mutually exclusive. The
upstream build system doesn't crash at the moment, but will instead
select only one of them if both are specified -- probably not what you
want! This new revision adds an at-most-one-of constraint for those
flags, so that you must explicitly choose (only) the one you want.

Future versions of FreeTDS will throw an error if you ask for both.

Package-Manager: Portage-2.3.6, Repoman-2.3.1
