`nix-collect-garbage --dry-run` previously elided the entire garbage
collection check, meaning that it would just exit the script without
printing anything.
This change makes the dry run flag instead set the GC action to
`gcReturnDead` rather than `gcDeleteDead`, and then continue with the
script. So if you set `--dry-run`, it will print the paths it *would*
have garbage collected, but not actually delete them.
I filed a bug for this: #432 but then realised I could give fixing it a go myself.

nix-collect-garbage --dry-run did not previously give any output - it simply
exited without even checking to see what paths would be deleted.
$ nix-collect-garbage --dry-run

We updated the behaviour of the flag such that instead it prints out how many paths it would delete, but doesn't actually delete them.
