kernel - Fix bugs in rdrand, change sampling frequency
* Fix bugs in the rdrand assembly. %ebx/%rbx is a call-saved register and
cannot be destroyed. For 64-bit use %r11 which is a temporary register.
* Increase the rdrand.c frequency from 1Hz to 10Hz
* add the debug.rdrand sysctl
* Use add_buffer_randomness() instead of add_true_randomness().
