guix system: 'guix system init' installs GRUB by default.
* guix/scripts/system.scm (install): Add #:grub?, #:grub.cfg, and #:device parameters; honor them. (show-help): Document '--no-grub'. (%options): Add '--no-grub'. (%default-options): Add 'install-grub?'. (guix-system): Honor 'install-grub?' option from OPTS. Adjust 'install' call accordingly. * doc/guix.texi (Invoking guix system): Document '--no-grub'.
