[PATCH v2 2/2] hw/core: loader: Set is_linux to true for VxWorks uImage

[Bin Meng]

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

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