perf tools: Fix thread comm resolution in perf sched
This reverts commit 9a92b479b2f088ee2d3194243f4c8e59b1b8c9c2 ("perf
tools: Improve thread comm resolution in perf sched") and fixes the
real bug.
The bug was elsewhere:
We are failing to resolve thread names in perf sched because the
table of threads we are building, on top of comm events, has a per
process granularity. But perf sched, unlike the other perf tools,
needs a per thread granularity as we are profiling every tasks
individually.
So fix it by building our threads table using the tid instead of
the pid as the thread identifier.
v2: Revert the previous fix - it is not really needed
