[PATCH] make-release: misc fixes

["Michael S. Tsirkin" <mst@redhat.com>]

This fixes /tmp usage in make-release script for security.
Also, create output directory if it does not exist.
This also adds a 'tarball' optin to specify output file name.
Finally, remote output file before gzip to avoid prompt
'do you want to overwrite'.
