RT#73202: LDIF.pm: Base64-encode values ending in spaces

Although not required by the RFC, Base64-encode those values that end in
spaces when writing LDIFs.
This makes it easier for the user to visually detect those values and
increases compatibility with other implementations (e.g. OpenLDAP's
ldapsearch).
