    guix system: List old generations from newest to oldest.
    
    Previously 'guix system switch-generation' or 'delete-generations' would
    yield a GRUB menu where entries for old generations were in the wrong
    order (i.e., oldest first.)
    
    * guix/scripts/system.scm (reinstall-bootloader): Reverse the list
    returned by 'generation-numbers'.
