Remove -container parts of profiling_view
Remove -container parts of profiling_view

This is partly because the container is unneeded, afaict. But,
more importantly, the styling is broken with this: the x-profiling-view-container is not stretching to fill x-profiling-view, so in about:tracing,
the UI doesn't fill the screen properly.
