Remove ldap_esc_vulnerable_cert_finder acceptance test

[jheysel-r7]

The acceptance tests for our LDAP modules get run against a docker container running OpenLDAP which does not support the LDAP whoami extended operation OID: 1.3.6.1.4.1.4203.1.11.3. This is a problem because the ldap_esc_vulnerable_cert_finder is meant to be run against a Windows AD LDAP environment which does support this OID. This means, unfortunately, at the current time we are unable to support testing this module.

Not a blocker; I think this test might still be useful to catch unexpected exceptions being raised in this module - i.e. unexpected ldap client failures etc
