[ImageBuilder 1/5] uboot-script-gen: Update to deal with uImage which is not executable

[Oleksandr Tyshchenko <olekstysh@xxxxxxxxx>]

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>

uImage is the Image that has a U-Boot wrapper, it doesn't contain
"executable" string which subsequent "file" command is looking for
when inspecting it.

Below the proof:

otyshchenko@EPUAKYIW03DD:~/work/xen_tests/input$ file -L binaries/uImage.gz
binaries/uImage.gz: u-boot legacy uImage, Linux Kernel Image, Linux/ARM 64-bit,
