open.2: minor: Fix O_CLOEXEC wording re fcntl() calls 

The current wording suggests that only a single fcntl()
operation is needed to set the FD_CLOEXEC flag, when "proper"
usage would be fcntl(F_GETFD) + fcntl(F_SETFD) to get the
flags and then update them.  So change the wording to indicate
that more than one fcntl() operation is required.
