autofs-5.0.5 - fix libxml2 workaround configure

From: Ian Kent <raven@themaw.net>

The configure logic related to work around the libxml2 library
reload issues is not quite right. The xml code is needed if
ldap is used so it is sufficient to require inclusion of the
workaround code if autofs is being built with LDAP support.
