LP#1586567 Always return Fund Years sorted descending

Currently, fund year selectors in Acq interfaces (at least Acq Admin ->
Funds, and Acq -> Load MARC Order Records) show the fund years in
database order. This commit adds a descending sort to the perl function
that retrieves fund years for those interfaces. It also removes the
unsuccessful attempt at sorting that was present in the dojo code.
