gpgtar: Make --status-fd option for fds > 2 work

Browse Source 
* tools/gpgtar-create.c (gpgtar_create): Do not close the status_fd in
spawn.
* tools/gpgtar-extract.c (gpgtar_extract): Ditto.
* tools/gpgtar-list.c (gpgtar_list): Ditto.
--

Note that this fix does not handle file descripotors passed via the
