This is a back-port of a commit from when trunk switched to python3
only. Since python2 is going EOL soon, and 6.0 LTS will outlive it, I
skipped the pull request step since:

- patch applied without a conflict
- it fixes all shebangs in 6.0
- our scripts are already py3-ready

I sent another email to this list to inform you that RHEL 8 bans the
unversioned /usr/bin/python version so in addition to saying goodbye
to py2 on all active branches this is also a necessary step to enable
el8 support in the future. For this reason I'm cross-posting on both
dev and commit mailing lists.

I'll leave it to Reza (CC'd) to include this in the changelog. Our 6.x
packaging already requires python3 anyway, it's just that if python2
is present in the build root it will no longer be used implicitly (or at all).
