Better alternative to !64 that doesn't require new gems and leaves dealing with string character encoding to gitlab-rails. See gitlab/gitlabhq!1701 for the corresponding changes there.

Remove recursive commands from bin/install

It is not clear what we need these for anymore. Because these commands
would recurse once through all existing files in all Git repositories,
and then another time through all directories these commands could
take very long on a server with a lot of repositories.

We keep the 'chmod' on config.repos_path, to deny world access to all
files and directories beneath it.
