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().
