Can we overload the ENOSYS return value and return it for CPUs without
hardware assisted random number generator? This way we certainly catch
real bugs in software that do not handle ENOSYS anyway.

This semantics should work great for linux compat as well.

       ENOSYS The glibc wrapper function for getrandom() determined that
              the underlying kernel does not implement this system call.
