Ticket 48815 - ns-accountstatus.pl - fix DN normalization

Bug Description:  When processing an entry DN the script breaks the entry
                  up into separate parts which are used in a filter.
                  These parts were not being normalized which leads to
                  the script failing.

Fix Description:  First improve the DN normalize function to strip both
                  starting and trailing spaces, then normalize the new
                  DN filter when searching for the backend.
