Subject: Install os-release(5) content to /usr/lib and have /etc/os-release be a symlink


When trying to use CentOS to build "stateless" systems or building nspawn
containers, the presence of os-release(5) data in /usr/lib/os-release is
expected. Not having this file causes problems for tools that expect
the data to be in /usr/lib/os-release and would regenerate the symlink
in /etc/os-release.
