guix system: List old generations from newest to oldest.

Browse source 
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'.
