system: Don't make /boot/grub/grub.cfg a symlink to the store.
This would not work when /boot is a separate partition, as reported by Nikita Karetnikov <nikita@karetnikov.org> in <http://bugs.gnu.org/19220>. This fixes a regression introduced in 39d1f82. * gnu/build/install.scm (install-grub): Copy GRUB.CFG instead of symlinking it, as was the case before 39d1f82. * gnu/build/vm.scm (register-grub.cfg-root): Add 'grub.cfg' parameter. Make it a permanent GC root instead of an indirect GC root. (initialize-hard-disk): Adjust accordingly. * guix/scripts/system.scm (install-grub*): Replace use of 'add-indirect-root' by the addition of a permanent GC root in %GC-ROOTS-DIRECTORY.
