oem-azure: add hyperv daemons

Browse Source 
This change adds hyperv daemons hv_fcopy, hv_kvp, and hv_vss to the
Azure OEM sysext. hv_kvp specifically is needed to submit OS version
information to the Azure hypervisor.

The daemons, tough userspace programs, are built from the kernel sources
as they are included in the Linux kernel.
