guix-install.sh: Add unique requirement for sysv init system

This improves the installer's ability to detect that all requirements are
present regardless of init system. It also avoids performing the requirement
check twice (printing excessively to the console) and provides a framework for
adding new init system specific requirements if it's needed in the future.

* etc/guix-install.sh (add_init_sys_require): Create.
(SYSV_INIT_REQUIRE): Create.
(main_install): Reorder installer steps so all requirements are checked in one
pass.
