nixos/nixos-enter: hide systemd-tmpfiles errors

Browse source 
Due to missing `/etc/machine-id` in the new root, systemd-tmpfiles
outputs a bunch of scary warnings like "Failed to replace specifiers in
'/run/log/journal/%m'". We only care about /tmp, so hide them.

`-E` is an alias for `--exclude-prefix=/dev --exclude-prefix=/proc
--exclude-prefix=/run --exclude-prefix=/sys`.
