Subject: Do not override nix.settings.build-dir

NixOS 25.11 contains Nix 2.30 which now builds to /nix/var/nix/builds,
which is not space constrained like the previous default of /tmp. To
perform the upgrade to NixOS 25.11, we first must unset our build-dir
from a world writable directory.

See https://github.com/nixos/nix/issues/13701
