The infrastructure runs everything already in Python3, so this is
mostly a clean-up.
For MB, a python2 holdover was removed and new lint errors were
fixed.
The renames were automated with:
git grep -e "/usr/bin/python$" |
cut -d':' -f1 |
xargs
sed -i 's/#!\/usr\/bin\/python$/#!\/usr\/bin\/python3/1'
and
git grep -e "/usr/bin/env python$" |
cut -d':' -f1 |
xargs
sed -i 's/#!\/usr\/bin\/env python$/#!\/usr\/bin\/env python3/1'

release builds.
