Revert "publish: Prevent publication of non-substitutable derivation outputs."

Fixes guix/guix#2450.

This reverts commit b5745a327e, which introduced
discrepancies in how substitutes are served; in particular, narinfos of
non-substitutable items would still be served, and likewise for narinfos and
nars of dependents of non-substitutable items.
