update/release: reproducibility test without xz

Browse Source 
in testing, between two linux distros, i got different src
tarball hashes, but same hashes when run twice on each

i'm using pretty solid options in tar, and riku came up
with the idea that maybe xz might be causing issue.

i'm ruling this out by running the release script with
this patch, on the same two systems, which will create
a .tar file instead, and i'll compare hashes.
