it's in 'lib/' for us.  This patch fixes that.

* 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".
