Subject: [PATCH] AK2: repair unpackelf support on repeat dirty flashes - on
 Sony devices supporting standard boot.img on unloacked bootloaders first AK2
 flash would convert from ELF to boot.img, but second flash would attempt to
 use unpackelf again and fail, so fallback to unpackbootimg - requires updated
 unpackelf binary for Sony ELF devices (see:
 https://github.com/osm0sis/unpackelf)
