java/openjdk*: Deprecate unmaintained versions

[haraldei]

Summary

This deprecates the non-lts versions of OpenJDK, to discourage
installing the, from the ports tree. I have not set a expiration date
for the ports yet, as I think it's worth discussing this a bit before
deciding on hard timeframes.

Test Plan

• None

[jrm]

Are we planning to remove these ports from the tree at some point? If so, you should also set EXPIRATION_DATE.

Ignore me. I somehow missed your comment above when I wrote this.
