libsysprof-gtk: show a list of backtraces on the right

Browse Source 
When selecting a callback node, show all a list of all of the traces where
that occurred on the right, so that you can select them individually.

Currently this only shows pid/time for on the right, but we'll add another
pane that will show the symbolized backtrace soon.
