[PATCH 1/2] selftests/damon: fix DamosFilter memcg_path assignment

[niecheng]

DamosFilter stores memcg_path for sysfs staging, but the constructor
assigns it with a trailing comma and therefore turns it into a tuple.

Fix the assignment so memcg_path is stored as the intended string.
This makes memcg filter staging and follow-up validation use the
written path correctly.
