Revert "librados: remove the unused flags."

This reverts commit 4bd2bd6bb89b70167de2f142008540238f682f6d.

These constants are the only way these flags are exposed through the C
interface. C users can't include librados.hpp.  Ideally we would have
only one version of these (just the C ones), but the C++ ones came
first and need to stay for backwards compatibility.
