ovs-atomic: Remove atomic_uint64_t and atomic_int64_t.

Some concern has been raised by Ben Pfaff that atomic_uint64_t may not be portable. In particular on 32bit platforms that do not have atomic 64bit integers. Now that there are no longer any users of atomic_uint64_t remove it entirely. Also remove atomic_int64_t which has no users.
