[PATCH 2/2] Fix <get-attachment> to remove attachments upon compose abort.

The files are copied to $tmpdraftdir, and are "owned" by the compose
process.  But they still had their unowned flag set.  So aborting the
compose would leave those files inside $tmpdraftdir.

Unset the flag so they are properly cleaned up.
