[oe] [meta-java][PATCH 3/5] openjdk-8-cross.inc: tweak PACKAGECONFIG default value

[liu.ming50 at gmail.com]

From: Ming Liu <peter.x.liu at external.atlascopco.com>

When x11, alsa is being set in DISTRO_FEATURES, the users might expect
openjdk build with the related options as well. For instance, they might
be confused when the openjdk is still built as headless but x11 is
actually enabled from system aspect.

With this patch, the end users still can choose build openjdk without
these options by overriding PACKAGECONFIG.

Two small fixes are also needed to let openjdk build with x11:
- Add libxtst to DEPENDS.
- Pass ac_x_includes and ac_x_libraries to configure command.
