Start the pager early-enough in nix why-depends
`nix why-depends` is piping its output into a pager by default. However the pager was only started after the first path is printed, causing it to be excluded from the pager output. (Actually the pager was started *inside* the recursive function that was printing the dependency chain, so a new instance was started at each level. It’s a little miracle that it worked at all). Fix #5911
