Remove orc 1.2 from apache distribution mirrors

[Owen O'Malley <ow...@gmail.com>]

All,
   Now that we've had 1.3 and 1.4 out for a while, I don't think there is
any need for the 1.2 release to remain on the Apache distribution site and
mirrors. If no one objects, I'll remove it at the end of the week. The bits
remain available it just moves it from "stable" to "archived" in our
release table (https://orc.apache.org/docs/releases.html#all-releases) and
means that the tarball isn't mirrored.
