MFC r234057: sem_open: Make sure to fail an O_CREAT|O_EXCL open, even if
that semaphore is already open in this process.

If the named semaphore is already open, sem_open() only increments a
reference count and did not take the flags into account (which otherwise
happens by passing them to open()). Add an extra check for O_CREAT|O_EXCL.
