This is a follow-on to RT-36848. The contents of the javafx-java.policy file, which will be appended to the standard java.policy file, are correct for desktop, but need to be adjusted for embedded (linux-arm) builds in the same way as was done for the javafx-ext-meta-index file.

For cross builds, the contents should be:

------------------------------------------------------------------------------------------------
grant codeBase "file:${java.home}/lib/ext/jfxrt-graphics.jar" {
        permission java.security.AllPermission;
};
grant codeBase "file:${java.home}/lib/ext/jfxrt-controls.jar" {
        permission java.security.AllPermission;
};
------------------------------------------------------------------------------------------------

which are the jars that are picked up by the embedded JDK build.
