The motivation for this is that I'm putting GNU tar on a file-descriptor
diet, and I needed O_CLOEXEC, which gnulib sometimes doesn't define.
It's more convenient for tar if gnulib defines O_CLOEXEC to 0 on platforms
that lack it, which is what gnulib already does for the other O_* flags.
This patch also adds O_EXEC. GNU tar doesn't need that, but might as well
add it while I'm in the neighborhood.
Ultimately, I would like to patch gnulib to support O_CLOEXEC even on
systems that lack it (such support would be via a non-atomic call to
fcntl after the fact but before the fd is given to the caller). But
this looks decent in the meantime.
