[U-Boot] [PATCH v1] fdt: Fix mkimage list to try every header type

[Jordan Hand]

Signed-off-by: Jordan Hand <jorhand at microsoft.com>
---
Image type is not supplied to `mkimage -l`. For this reason, we cannot
use imagetool_verify_print_header_by_type. Instead, this patch uses
imagetool_verify_print_header to look through all header types to find
one where image validation succeeds.

This patch fixes failures in test/image/test-imagetools.sh
