[PATCH 2/2] hw/core: loader: Setting is_linux to true for VxWorks uImage

[Bin Meng <bmeng.cn@gmail.com>]

From: Bin Meng <bin.meng@windriver.com>

VxWorks 7 now uses the same boot interface as the Linux kernel on
Arm64, PowerPC and RISC-V architectures, except Arm. Add logic to
set is_linux to true for VxWorks uImage for these architectures in
load_uboot_image().
