git: Periodically delete least-recently-used cached checkouts.
This ensures ~/.cache/guix/checkouts is periodically cleaned up.
* guix/git.scm (cached-checkout-expiration)
(%checkout-cache-cleanup-period): New variables.
(delete-checkout): New procedure.
(update-cached-checkout)[cache-entries]: New procedure.
Add call to 'maybe-remove-expired-cache-entries'.
* guix/cache.scm (file-expiration-time): Add optional 'timestamp'
parameter and honor it.
