Fix a crash if AudioTrack fails to initialize

AudioTrack constructor is badly return. It can fail by throw an exception, and it can also silently fail without notifying the caller.
We have to call AudioTrack.getState() to check the AudioTrack status.

This CL adds a call to layout in --dump-render-tree's fake implementation of

compositor, which doesn't exist when running with --dump-render-tree.
