android: boot: replace android_image_check_header

Browse source 
With the new vendor boot image introduced in versions 3 and 4
of boot image header, the header check must be done for both boot
image and vendor boot image. Thus, replace android_image_check_header()
by is_android_boot_image_header() to only refer to boot image header check.
