This reverts commit d34a7b3.

The reverted commit moved the collection of Cilium profiling data as first task, to prevent it from being impacted by the other sysdump collection tasks. However, the current approach has the unintended consequence of collecting each pprof sequentially, hence taking a significant amount of time, proportional to the number of nodes (approximately one hour with 100 nodes). Let's revert this for now, while figuring out a better approach to achieve the same goal.
