This reverts commit 9effefbae8d96006a4dd29bb9ab8532fd408559d.
With the include order in ScriptedProcessPythonInterface.cpp fixed
(though I cannot explain exactly why it works) and removes the /H flag
intended for debugging this issue.
I think it is something to do with Process.h pulling in PosixApi.h
somewhere along the line, and including Process.h after lldb-python.h
means that NO_PID_T is defined to prevent a redefinition of pid_t.
