gnu: ldns: Do not depend directly on nss-certs.

If ldns depends on a particular version of nss-certs, the features that use the
certificates will eventually stop working as the certificates expire. Instead,
the certificates should be found at run-time.

* gnu/packages/dns.scm (ldns)[inputs]: Remove nss-certs.
[arguments]: Adjust the value of "--with-ca-path" in #:configure-flags.
