android: boot: support vendor boot image in abootimg
Vendor boot image is introduced in boot image header version 3 and 4. Please check [1] for more details. To prepare for boot image v3/v4 support, allow the abootimg command to store the vendor_boot image address. Full support for this new format will be done in a future patch.
