[v2,1/4] power: make guest channel headers public

  The channel commands header file contains definitions that are used by the
example application for power management, and so need to be made public.
Similarly the guest_channel.h header is used by the guest_cli example
utility, so needs to be public also.  Without this change, the example
apps, or any end-user apps based on them, can not be compiled outside the
main DPDK build.

Fixes: 210c383e247b ("power: packet format for vm power management")
Fixes: cd0d5547e873 ("power: vm communication channels in guest")
