Set a fixed install dir and add specific prereqs

* Install build artifacts to a fixed dir rather than attempting
  to infer a location based on the Python binary location.  That
  was intended to work seamlessly in venvs, we'll burn that bridge
  when we come to it, for now just put it all in
  $DEST/usr/{bin|include|lib}.  This also removed the need for
  root access for these files to allow the build steps to be performed
  on laptops that may not otherwise run DevStack.

* Handle some side-effects of a non-default install location for
  the build artifacts.

* Add missing CentOS prereqs for base image builds:
  fm-common:
  - libuuid-devel
  - postgresql-devel

* Add the declarations to settings for the devstack playbook to
  handle plugin precedence order properly.
