Fix asym_wrap_test on 32-bit architectures `C_WrapKey` and `C_UnwrapKey` use `CK_ULONG` for the wrapped key size, which isn't the same as `size_t` on all architectures. This caused "passing argument ... from incompatible pointer type" errors on Debian i386.
Don't assume that sizeof(time_t) == sizeof(long) On some architectures, such as Debian's 32-bit armel and armhf architectures after their recent migration to 64-bit `time_t`, the `time_t` and `long` types are not the same size. Fix `yh_com_benchmark` to avoid assuming that they are.
