* Make the --prebuilt-only' / -b' option work not just for queries

but installations/upgrades as well.  So `nix-env -ub \*' will
  upgrade only those packages for which a substitute is available (or
  to be precise, it will upgrade each package to the highest version
  for which a substitute is available).
