unrevert r63852 but keep SIGCHLD path disabled for win32
Reading win32/win32.c waitpid implementation, maybe waitpid(-1, ...) on that platform will never conflict with mjit use of waitpid.
In any case, I've added WAITPID_USE_SIGCHLD macro to vm_core.h so it can be easy for Linux/BSD users to test (hopefully!) win32-compatible code.
