This is a followup to a1cd93083b.

* gnu/packages/package-management.scm (guix)[arguments]: Refer to
"guile-gnutls" instead of "gnutls".
[native-inputs, propagated-inputs]: Replace 'gnutls' with 'guile-gnutls'.
[inputs]: Add 'zlib'.
(guix-daemon): Replace 'gnutls' with 'guile-gnutls'.
(guix-build-coordinator)[arguments, propagated-inputs, native-inputs]:
Replace 'gnutls' with 'guile-gnutls'.
(guix-build-coordinator/agent-only): Likewise.
(nar-herder): Likewise.
