Remove RPM specfile support for non-RedHat systems

RPM specfile support for non-RedHat systems is being dropped since
it has become a maintenance burden to maintain multiple distros
in the same specfile, especially with the transition to systemd.
Packaging details like this are best handled downstream.

The specfile will target the latest CentOS release.  RPM specfiles for
other distros & releases will be placed in a contrib subdir if needed.
