Remove a possible existing store path when building CA derivations In case a previous interrupted build left a garbage path laying around, remove it before trying to move the path to its final location. Fix #4858

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`

Non-blocking garbage collector The garbage collector no longer blocks other processes from adding/building store paths or adding GC roots. To prevent the collector from deleting store paths just added by another process, processes need to connect to the garbage collector via a Unix domain socket to register new temporary roots.
