regnat addacfce4a Allow running all the tests with the daemon
When `NIX_DAEMON_PACKAGE` is set, make all the tests use the Nix daemon.
That way we can test every piece of Nix functionality both with and
without the daemon.

Tests for which using the daemon isn’t possible or doesn’t make sens can
selectively be disabled with `needLocalStore`
