system: Initialize console keyboard layout in the initrd.
Partially fixes <https://bugs.gnu.org/25453>. * gnu/system.scm (<operating-system>)[keyboard-layout]: New field. (operating-system-initrd-file): Pass #:keyboard-layout to MAKE-INITRD. * gnu/system/linux-initrd.scm (raw-initrd): Add #:keyboard-layout. Pass #:keymap-file to 'boot-system'. (base-initrd): Add #:keyboard-layout. [helper-packages]: Add LOADKEYS-STATIC when KEYBOARD-LAYOUT is true. Pass #:keyboard-layout to 'raw-initrd'. * gnu/build/linux-boot.scm (boot-system): Add #:keymap-file and honor it. * doc/guix.texi (operating-system Reference): Document the 'keyboard-layout' field. (Initial RAM Disk): Update 'raw-initrd' and 'base-initrd' documentation.
