David Scott d24d0bd559 Add pkg/host-timesync-daemon ...

Some hypervisors (e.g. hyperkit / xhyve) don't provide a good way to keep
the VM's clock in sync with the Host's clock. NTP will usually keep the
clocks together, but after a the host or VM is suspended and resumed the
clocks can be suddenly too far apart for NTP to work properly.

This simple daemon listens on an AF_VSOCK port and resynchronises the VM
clock from the virtualised hardware clock.
