I do not like this one, we may end up redefining wrong priv and break
everything.

Given that the private stil exists in the structure for C code:

(/usr/include/linux/keyctl.h)
/* keyctl structures */
struct keyctl_dh_params {
        union {
#ifndef __cplusplus
                __s32 private;
#endif
                __s32 priv;
        };
        __s32 prime;
        __s32 base;
};

We may as well use private in the tests consistently and update our
fallback with the union as well.
