In Sagami we need to set the header-version for this bootimage to make vendor_boot possible (unfortunately AOSP does not do this for us based on the value of BOARD_BOOT_HEADER_VERSION (yet?)). Since CommonConfig is included all the way at the end of the respective PlatformConfig this wouldn't be possible when the value is overwritten here.
