Ludovic Courtès d921c742b7 cache: Avoid cache cleanup storms from concurrent processes. ...

Reported by Christopher Baines <guix@cbaines.net>.

* guix/cache.scm (maybe-remove-expired-cache-entries): Define
‘expiry-port’; create it with ‘lock-file’.  Change ‘last-expiry-date’
accordingly.  Write timestamp straight to ‘expiry-port’.
* tests/cache.scm ("maybe-remove-expired-cache-entries, cleanup needed
but lock taken"): New test.
