[Wang Mingyu]

From: Wang Mingyu <wangmy@fujitsu.com>

Add patch to fix ptest error:
The test_toml_roundtrip test requires tomli_w for TOML serialization
comparison. Skip this specific test while allowing all other tests to run.

+Subject: [PATCH] tests: Handle missing tomli_w gracefully in test_pylock.py
+
+The test_toml_roundtrip test requires tomli_w for TOML serialization
+comparison. Since tomli_w is not available, skip this
+specific test while allowing all other tests to run.
