Subject: selftests/damon/sysfs.py: clean up sh processes used for obsolete_target test
Date: Mon, 31 Aug 2026 07:26:06 -0700

The obsolete_target test spawns three sh processes and uses their pids as
DAMON monitoring targets.  These processes are never terminated or waited
on, so they are left running (or become zombies) as orphaned children
after the test program exits.

Terminate each process and communicate() with it after the targets are no
longer needed, so it exits and gets reaped instead of being leaked.
