coreutils: fix unprivileged sandbox build

In usernamespaces some POSIX assumptions break, which
make some coreutils fail when running with sandbox but without a nix-deamon.
With this pull request it is possible to bootstrap stdenv without root-permission,
which is quiet useful in HPC environments.
