system: vm: Support cross-compilation.
* gnu/system.scm (system-linux-image-file-name): Add support for cross-built systems. Remove system argument that was ignored, (operating-system-kernel-file): adapt by removing ignored os argument. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Add target argument and turn inputs into native-inputs. Pass target to qemu-command and gexp->derivation calls. (iso9660-image): Add target argument and pass it to expression->derivation-in-linux-vm. Remove qemu from inputs as it is not necessary. (qemu-image): Add target argument, also remove qemu from inputs. Pass target argument to expression->derivation-in-linux-vm call.
