<AWT Dev> [7u6] Review request for 7181027: [macosx] Unable to use headless mode

Since GraphicsEnvironment is a shared class, I'm concerned with removing
the check for "sun.awt.HeadlessGraphicsEnvironment" to determine whether
we should run in headless mode. Can we keep this check in place, and
also add the new one that checks the toolkit name?

The problem here is that for headless mode "java.awt.graphicsenv" system property should be CGraphicsEnvironment because the way GraphicsEnvironment.createGE() method works: it first instantiates GraphicsEnvironment instance and then wraps it with HeadlessGraphicsEnvironment if in headless mode. This means twe can't use java.awt.graphicsenv property to determine whether we are in headless mode or not. So, I've replaced it with a toolkit check: if it's HToolkit, then we are in headless.
