guix-package: Allow `--roll-back' to skip missing generations.
* guix-package.in (profile-numbers): New procedure.
(latest-profile-number): Use it.
(previous-profile-number): New procedure.
(roll-back): Use it lieu of `1-'. Check whether PREVIOUS-NUMBER is
zero, and raise an error when it is.
* tests/guix-package.sh: Test whether we can roll back over a "hole".
