class/kernel: Ensure that uImage file is used when USE_kernel_uimage is set

When setting the USE_kernel_uimage flag the image file will be named uImage

Example Config: USE_kernel_imagetype = vmlinux, USE_kernel_uimage=1.
The uImage is created in do_compile_kernel_uimage() (hardcoded to
uImage) and placed in boot/ not the vmlinux (which will end up in
kernel-vmlinux).
