HV: Make: enable build for new configs layout

The make command is same as old configs layout: under acrn-hypervisor folder: make hypervisor BOARD=xxx SCENARIO=xxx [TARGET_DIR]=xxx [RELEASE=x] under hypervisor folder: make BOARD=xxx SCENARIO=xxx [TARGET_DIR]=xxx [RELEASE=x] if BOARD/SCENARIO parameter is not specified, the default will be: BOARD=nuc7i7dnb SCENARIO=industry Tracked-On: #5077 Signed-off-by: Victor Sun <victor.sun@intel.com> Reviewed-by: Jason Chen CJ <jason.cj.chen@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
