cache: Avoid potential file descriptor leak.

There fixes two cases where ‘maybe-remove-expired-cache-entries’ could leak
‘expiry-port’ (in which case the underlying file descriptor would be closed
later, when ‘expiry-port’ gets GC’d.)

* guix/cache.scm (maybe-remove-expired-cache-entries): When ‘obsolete?’
returns false, explicitly close ‘expiry-port’.  When it returns true, catch
errors around ‘seek’ block and close ‘expiry-port’ upon exception.  Remove
ENOENT handling and comment that predates commit
