[PATCH 2/5] selftests/damon: fix memcg filter path handling

[Kunwu Chan <kunwu.chan@linux.dev>]

From: Kunwu Chan <kunwu.chan@gmail.com>

A trailing comma in the memcg_path assignment makes
memcg_path a single-element tuple instead of a string.

As a result, an invalid value is written to sysfs and memcg
filter configuration fails.

Remove the comma.
