Subject: [PATCH] Fix release RC stamping & tarball ownership

The ability to release 4.XX.Y via hardcoding a version.sh as part of
release broke the ability to do properly versioned RC releases.  Fix
that.

Try to fix ownership of files in tarballs to not be local system user.

(cherry picked from commit 7677a8673f89843326aab3944e608c6be4339039)
