daemon: runChild() is forbidden to talk during environment set up 

DerivationGoal::startBuilder() is waiting for an empty line as a check that
the environment set up is fine.

Fixes <https://issues.guix.gnu.org/55324>.

* nix/libstore/build.cc (DerivationGoal::runChild): Remove 'debug'
statement corresponding to bind mounts.
