libbluray: fix withJava

JAVA_HOME was always broken, it should have been JDK_HOME (however a fix
for that has been needing review for more than a year).

With libbluray 1.4.0, this is now set via the Meson flag `jdk_home`.
Additionally, headless JDK is no longer sufficient as it requires
`java.awt.Toolkit` at runtime.
