rS342731: Configure hz=100 in the QEMU target.

Summary

This is standard for VM guest kernels. However, we currently have no
good way to detect that we're running in a VM; there are various
machine-mode CSRs (e.g., mimpid) that can in principle be used to
determine this sort of thing, but as far as I can see they are not
available in supervisor mode.
