daemon: Handle EXDEV when moving to trash directory.
Fixes <https://bugs.gnu.org/41607>. Reported by Stephen Scheck <singularsyntax@gmail.com>. * nix/libstore/gc.cc (LocalStore::deletePathRecursive): When we try to move a dead directory into the trashDir using rename(2) but it returns an EXDEV error, just delete the directory instead. This can happen in a Docker container when the directory is not on the "top layer".
