guix-build: Add `--system'.
* guix-build.in (derivations-from-package-expressions): New `system' parameter. Pass it to `package-derivation'. (%default-options): Add `system' pair. (show-help): Describe `--system'. (%options): Add it. (guix-build): Check the `system' pair in OPTS; pass it to `derivations-from-package-expressions' and `package-derivation'.
