Include launched packageName in systrace.

This makes it easier to tell which package the activity manager is
launching. The downside here is that each launch shows up in a separate
row in the systrace, but this matches up with the "Start proc:" label,
which contains the package name as well and makes it easier to inspect
both simultaneously.
