[PATCH v2 3/4] perf test: Suppress optparse deprecation warning with older pylint

[Leo Yan]

Python 3.13 reversed optparse's deprecation, and pylint 3.3.5 removed it
from the deprecated-module list. Perf supports older pylint versions,
so suppress the warning on this import and document the reason. Keep
other deprecated-module diagnostics enabled.
