doc string for global-hl-line-mode should not mention M-x customize

[Drew Adams]

C-h v already adds "You can customize this variable". The doc string
should not also have this text: "use either M-x customize...".  The
link on this occurrence of "customize" does not take you to the
Customize buffer for the option; it takes you to the doc string of
command `customize', which is undesirable here.
