perf python: Remove PYTHON_PERF ifdefs

When perf code was compiled one way for the binary and another for the
python module, the PYTHON_PERF ifdef was used to remove some code from
the python module.

Since switching to building the perf code as a series of libraries, with
the same libraries being used for the python module, the ifdefs became
unused as PYTHON_PERF is never defined. As such remove the ifdefs.
