linux-initrd: Ensure that the guile used in the initrd is referenced.
By referencing guile from the initrd output explicitly, it will be present in the store when this initrd is used. If the exact guile used within the initrd isn't present in the store, then after root is switched during the boot process, loading modules (such as (ice-9 popen)) won't work. This fixes guix-patches bug #28399, "Fix mysql activation, and add a basic test". * gnu/system/linux-initrd.scm (expression->initrd)[builder]: Write out a file called references in to the initrd output, which includes the store path for guile.
