roken: use Win32 rand_s() for rk_random() when available
On Windows if the compiler and C RTL is >= 1400 then the rand_s()
function is available. rand_s() unlike rand() makes use of the
RtlGenRandom() API to produce a random number between 0 and UINT_MAX.
If rand_s() is not available or fails, fallback to rand().
One of the benefits of rand_s() is that no initialization is required
so it will provide random output even if rk_random_init() is not called.
