fix: CVE_2024_50379

[SalwaAdlouni]

This pull request refines the vulnerability detection logic for CVE-2024-50379 and updates the corresponding test to use synchronous mocking. The main change ensures that the race condition test is only run if the Tomcat version is vulnerable, improving both accuracy and efficiency.

Vulnerability detection logic:

• In agent/exploits/cve_2024_50379.py, the code now checks if the Tomcat version is vulnerable before running the race condition test, ensuring the test is only performed when relevant.

Testing improvements:

• In tests/exploits/cve_2024_50379_test.py, the race condition test mock is switched from an asynchronous mock to a synchronous mock to match the updated logic.
