Downport JDK-8212828 (posix_spawn on Linux as non-default) to 11u

[Roger Riggs]

Hi Thomas,

We'll also need a retroactive CSR for JDK 12 to change its status in JDK 
12 to be documented.
Can you take a swing at that?
On the Jira issue[2] there is a "More" menu  with a 'Create CSR' button.
It comes pre-filled with a template that should be pretty 
straightforward to fill out.

A CSR will also be needed for JDK 11 (pretty much a copy).
In the compatibility section, point out that it does not change the default.

I created a draft release note for JDK 12 [1].
Please review and comment or edit it directly with suggestions.
There is a release note style guide for reference [3].

Thanks, Roger
