nix-collect-garbage: Fix deleting old generations
The call to nix-env expects a string which represents how old the
derivations are or just "old" which means any generations other than
the current one in use. Currently nix-collect-garbage passes an empty
string to nix-env when using the -d option. This patch corrects the call
to nix-env such that it follows the old behavior.
