nixos/sssd-ldap: fix eval

Introduced by fd7d901133f9fbfc893cdb33f7d630846bb21f9c. The openldap
module now expects the database directory to be below
`/var/lib/openldap`, oterhwise it'll fail evaluation like this:

    Failed assertions:
    - Database dc=example,dc=org has `olcDbDirectory` (/var/db/openldap) that is not a subdirectory of
    `/var/lib/openldap/`.
