publish: Explicitly update the atime for cache expiry.

Mounting file systems with ‘noatime’ is common.  Thus, avoid relying on the
atime.

hit.  Use ‘stat’ instead of ‘file-exists?’.

inferior: Caching works by checking the mtime, not the atime.

Mounting file systems with ‘noatime’ is common.  Thus, avoid relying on the
atime.

* guix/inferior.scm (cached-channel-instance): Pass ‘stat:mtime’ to
‘file-expiration-time’.  When ‘cached’ exists, call ‘utime’ to update its
mtime and atime.

Change-Id: Ib9bff45ed402260fdead3c23f09b431fa369e741

shell: Don’t rely on atime for caching.

Relying on atime was fine even on ‘noatime’ file systems because the atime was
explicitly updated.  However, on file systems with atime enabled, cache items
were potentially retained for too long since scanning the cache directory
could update atimes.

* guix/scripts/shell.scm (options-with-caching): In ‘utime’ call, change both
the mtime and the atime.
(guix-shell)[entry-expiration]: Use ‘file-expiration-time’ with ‘stat:mtime’.
