HPCC-17080 System built with USE_OPENLDAP=0 doesn't start

ESP Service ws_access gets loaded and initialized even it HPCC was
built without LDAP support. This causes it to throw an exception
when binding, causing ESP to not load.  This PR modifies ESP to only
load ws_access if LDAP has been built in
