install script: don't abort when "nix-channel --update" fails
Instead, print a message about what happened and tell the user what can
be done (run "[sudo -i] nix-channel --update nixpkgs" again at a later
time). This change allows installing Nix when you're offline.
Since the multi-user installer is so verbose, the message isn't printed
until the end.
Fixes issue #2650 ("installation without internet connection").
