Fix fixup_stuff.sh package permissions fix

There are a number of different attempts to fix this issue, specifcally on RHEL6.
None of them actually get it right.
* This does not upgrade an OS installed package because we trust them to not make
  these sorts of permissions mistakes. Also we do not have nor want to figure out the
  right version that the OpenStack projects will require.
* This specfically targets the upstream package versions as we do not know how
  later versions behave.

This should address the following reviews:
