Subject: [PATCH] misc: Fix python scripts shebang line

Type: fix

Since CentOS 8, RPM build script doesn't accept '#!/usr/bin/env python'
as a valid shebang line.  It requires scripts to explicitly chose
between python2 or python3.

Change all to use python3 as suggested by Paul Vinciguerra.

Depends-On: https://gerrit.fd.io/r/23170
