selftests/damon/sysfs.py: validate memcg_path staging readback

Browse source

Add a dedicated test at the end of main() that stages memcg_path via sysfs
and verifies its readback.  Configure the memcg filter before start(), do
not call commit(), and ignore start() failures so the test does not depend
on CONFIG_MEMCG or cgroup layout.  Call stop() for cleanup without
checking its return value.
