Avoid generating SSL certs for LDAP tests

We don't generate SSL certificates for running the SSL tests, but
instead use pregenerated certificates that are part of our source code.
This patch applies the same policy to the LDAP tests, and in fact simply
reuses certificates from the SSL test suite by copying them. It won't
save much but it should save a handful of cycles at run time.
