[PATCH v2 1/2] selftests/damon/_damon_sysfs.py: fix memcg_path assignment

[Cheng Nie]

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.
