Moves runHook to a later execution position

It moves runHook to a later position in the rcfile. After that we are
able to set the PS1 environment-variable for a nix-shell environment
e.g.:

  # turn the color of the prompt to blue
  shellHook = ''
    export PS1="\n\[\033[1;34m\][\u@\h:\w]$\[\033[0m\] ";
  '';
