local-derivation-goal.cc: downgrade "warning: rewriting hashes in..." down to debug

Browse source 
Before the changes when building the whole system with
`contentAddressedByDefault = true;` we get many noninformative messages:

    $ nix build -f nixos system --keep-going
    ...
    warning: rewriting hashes in '/nix/store/...-clang-11.1.0.drv.chroot/nix/store/...-11.1.0'; cross fingers
    warning: rewriting hashes in '/nix/store/...-clang-11.1.0.drv.chroot/nix/store/...-11.1.0-dev'; cross fingers
    warning: rewriting hashes in '/nix/store/...-clang-11.1.0.drv.chroot/nix/store/...-11.1.0-python'; cross fingers
    error: 2 dependencies of derivation '/nix/store/...-hub-2.14.2.drv' failed to build
    warning: rewriting hashes in '/nix/store/...-subversion-1.14.1.drv.chroot/nix/store/...-subversion-1.14.1-dev'; cross fingers
    warning: rewriting hashes in '/nix/store/...-subversion-1.14.1.drv.chroot/nix/store/...-subversion-1.14.1-man'; cross fingers
    ...

Let's downgrade these messages down to debug().
