openjdk-8: add recipes for openjdk-8 and openjre-8

This adds openjdk-8 for native and target builds and allows a stripped
openjre-8 being built as well instead of trying to cherry-pick jre
components from jdk-image.

The recipes allow building openjdk-8 with or without:
* x11
* cups
* alsa/pulseaudio
and let packager enable unlimited-crypto, if desired.

To support certificate based java libraries, cacerts is created based on
ca-certificates from OE-core.

Since there can be only one PROVIDES for virtual/java-native and virtual/javac-native,
move the provides to openjdk-8-native (I think everyone agrees it's a better
choice than ecj-bootstrap-native).

Plus: Applying a fix from openjdk-9 repository which fixes build issues using gcc5
