From: "Zenghui Yu (Huawei)" <zenghui.yu@linux.dev>
The sysfs_no_op_commit_break test starts a kdamond via sysfs, but its error
paths (e.g., drgn not installed) exit without stopping it. The leaked
kdamond then makes subsequent tests, e.g. lru_sort.sh and reclaim.sh, skip
with "Another kdamond is running".
Wrap the post-start logic in try-finally so that kdamonds.stop() is
executed on every exit path.

sysfs.py and sysfs_no_op_commit_break.py dump the DAMON status collected
via drgn_dump_damon_status.py into a damon_dump_output file in the working
directory. Ignore it so that running the tests in-tree does not pollute
git status.

From: Eva Kurchatova <eva.kurchatova@virtuozzo.com>
Running these tests under Python's safe path mode, either with -P on the
interpreter command line or with PYTHONSAFEPATH set in the environment,
stops the script's own directory being prepended to sys.path. Some
distributions (RHEL, for example) build the tests with -P in the shebang.
This breaks all 7 DAMON Python selftests that import the _damon_sysfs
helper module located in the same directory:
ModuleNotFoundError: No module named '_damon_sysfs'
Fix this by explicitly adding the script's directory to sys.path before
importing _damon_sysfs, following the same pattern used in commit
c3b3eb565bd7 ("tools: ynl: add script dir to sys.path") which fixed the
identical issue for the YNL tools.

Test the zero sample interval case with a non-zero aggregation
interval, and keep the zero/zero case to cover the zero-result
fallback.
Also make the overflow case use an explicit sample interval so that
it does not depend on the zero sample interval fallback.

qt_exceeds counts how many times a scheme's quota has been exceeded.
When using the temporal auto-tuning algorithm, the effective size quota
becomes zero once the goal is [over-]achieved. In this case, the quotas
are still set, so qt_exceeds keeps increasing once per quota reset
interval while the goal stays achieved.
Clarify this behavior in the design document.
