gnu: Add (gnu system).
* gnu/system/vm.scm (lower-inputs): Move to monads.scm. (qemu-image): Don't add GRUB-CONFIGURATION to the INPUTS-TO-COPY. (union, file-union, etc-directory): Move to gnu/system.scm. (%demo-operating-system): New variable. (system-qemu-image): Add 'os' parameter. Rewrite in terms of 'operating-system-derivation'. * guix/monads.scm (lower-inputs): New procedure. * gnu/system/grub.scm (grub-configuration-file): Change 'entries' to be a plain list instead of a list of monadic values. * gnu/system.scm: New file. * gnu-system.am (GNU_SYSTEM_MODULES): Add it.
