package[-static].bash: stop leaking the local user id in the tarball

The local user id of the packager is not interesting for users who
download the tarball.

Also it will cause the gocryptfs binary to have an unintended owner
when the tarball is extraced as root.

Fix the issue by using "tar --owner=root --group=root" which
overwrites user and group id with zero.
