Drop setcap on python binary
Drop setcap on python binary

This is a bit of a security issue, also we don't seem to need it anymore
since we have long switched to running under python3 and the setcap
doesn't have any effect anyway. It will also break deployments once we
drop installing python2 completely, so just remove it now.
