nixos/openldap: add option for configuring OpenLDAP package to use

In certain cases, for example when custom OpenLDAP modules are
compiled into the binary, users may want to override the package used
for OpenLDAP.

This is especially common in setups where LDAP is the primary
authentication source, as good password hashing mechanisms need to be
enabled as extra modules.
