Undo "bump the repack suffix"

Bumpin the repack suffix is the right thing to do when we touch the
vendor list, so that the orig tarball is recreated.

However this breaks the CI, which tries to generate the upstream tarball
with gbp, and I guess if I touch the repack suffix, I need to update the
pristine-tar and the upstream branches...

Let's just revert for now, I feel like opening a can of worms...
