[PATCH] githooks documentation: add a note about the +x mode

[Miklos Vajna <vmiklos@frugalware.org>]

In a freshly initialized repo it is only necessary to rename the .sample
hooks, but when using older repos (initialized with older git init)
enabled the +x mode is still necessary - docuement this.
