build-system: chicken: Add version information to eggs if missing.

Chicken eggs do not always contain version information, yet dependant packages
often rely on this information being present.  Thus, add a version field if it
is missing.

* guix/build/chicken-build-system.scm (stamp-egg-version): New variable.
(%standard-phases): Add ‘stamp-egg-version’.

;; It doesn't look like Chicken generates any unnecessary references.
