perfetto-ui: Stop drawing behind scrollbar

Previously the trace was drawn behind the scrollbar, so the end of the
trace was never visible. Now we calculate the width of the scrollbar
and subtract it from the canvas width. This means we can still have
the advantage of using all screen real estate when the scrollbar is
overlayed (and has width of 0).
