[RFC PATCH v2 6/6] selftests/damon: remove unused imports of os and sys modules

[SJ Park]

sysfs_no_op_commit_break.py imports 'sys' module but never uses it.
sysfs_update_schemes_tried_regions_hang imports 'time' module but never
uses it.  Remove the unnecessary imports.

The issue is found using flake8.
