Attached patch is avoids a syscall in os.set_inheritable() if the FD_CLOEXEC flag is already set/cleared.

The change only impacts platforms using fcntl() in _Py_set_inheritable(). Windows has a different implementation, and Linux uses ioctl() for example.

The same "optimization" is used in socket.socket.setblocking(): see the issue #19827.
