[lldbsuite] The test inside TestOverloadedFunctions.py has the wrong class name

[stella.stamenova]

Summary

It looks like the test file was copied from TestCPPStaticMethods.py because they have the same name. This means that the two tests will try to write to the same output files and will either overwrite each other's output or occasionally cause failures because they can't both access the same file.
