Recently the nss-tools dependency was removed from 389-ds-base.spec:
https://src.fedoraproject.org/rpms/389-ds-base/c/31b818c739ceee72e0ab4179c879d8efeacf2ba4?branch=f36

If 389-ds-base package was installed without nss-tools, dscreate will
fail because it's still calling certutil.

Steps to reproduce:
1. Install 389-ds-base without nss-tools
2. Use dscreate to create a basic DS instance

Actual result: DS instance creation failed (see dscreate logs below).
Expected result: DS instance should be created successfully.

dscreate logs:
