openjdk8: switch upstream to the openjdk BSD community effort at github

This repo is a continuation of the bsd-port tree, still maintained by
the FreeBSD ports java people.
It is forked from (and merges regularly from) AdoptOpenJDK.
They accept patches for other BSDs, so we should see if we have anything
in our tree worth contributing.

As a side effect, this changes updates openjdk8 to u222.
