Fix LLDB windows build

[omjavaid]

Summary

LLDB WoA buildbot is failing due to pid_t redefinition after recent changes in lldb/source/Plugins/ScriptInterpreter/Python/ScriptedProcessPythonInterface.cpp.
Process.h includes PosixApi.h which defines pid_t. Python.h on windows also typedefs
pid_t. To make sure that we include Python.h before PosixApi this patch renforces
the workaround previously set up to guard this issue.
