hg: openjfx/8/graphics/rt: Minor gradle script fixes. Fixed debug symbol generation for class files to match what we do normally (always generate them, just generate different sets of symbols depending on debug or not). Make sure not to include empty dirs in the final jfxrt.jar. Minor change to javafx.policy to make it exactly the same as our current file (doesn't really matter)
