kernel: use systemimage_intermediates on devices with no vendor 
Change I8b6040e03589bde2af4e161c891ded237a9bb335 did not account for
devices without a separate vendor partition, causing build to fail with
the following:

FAILED: ninja: '/file_list.txt', needed by 'out/target/product/joan/obj/KERNEL_OBJ/arch/arm64/boot/Image.gz-dtb', missing and no known rule to make it

Use systemimage_intermediates instead on said devices.

Test: m kernel

# Android makefile to build kernel as a part of Android Build
#
# Configuration
# =============
#
# These config vars are usually set in BoardConfig.mk:
#
# TARGET_KERNEL_ADDITIONAL_FLAGS = Additional make flags, optional
# TARGET_KERNEL_CONFIG = List of kernel defconfigs, first one being the base one,
# while all the others are fragments that will be merged
# to main one in .config.
# TARGET_KERNEL_RECOVERY_CONFIG = Same as above, but applicable to recovery kernel instead.
# TARGET_KERNEL_VARIANT_CONFIG = Variant defconfig, optional
# TARGET_KERNEL_SELINUX_CONFIG = SELinux defconfig, optional
#
# TARGET_KERNEL_CLANG_COMPILE = Compile kernel with clang, defaults to true
#
# BOARD_KERNEL_IMAGE_NAME = Built image name
# for ARM use: zImage
# for ARM64 use: Image.gz
# for x86 use: bzImage
# for uncompressed use: Image
# If using an appended DT, append '-dtb'
# to the end of the image name.
# For example, for ARM devices,
# use zImage-dtb instead of zImage.
#
# BOARD_DTB_CFG = Path to a mkdtboimg config file for dtb.img
#
# BOARD_DTBO_CFG = Path to a mkdtboimg config file
#
# BOARD_CUSTOM_DTBIMG_MK = Path to a custom dtbimage makefile
#
# BOARD_CUSTOM_DTBOIMG_MK = Path to a custom dtboimage makefile
#
# KERNEL_CC = The C Compiler used. This is automatically set based
# on whether the clang version is set, optional.
#
# KERNEL_CLANG_TRIPLE = Target triple for clang (e.g. aarch64-linux-gnu-)
# defaults to arm-linux-gnu- for arm
# aarch64-linux-gnu- for arm64
# x86_64-linux-gnu- for x86
#
# KERNEL_LTO = Optional, force LTO to none / thin / full
#
# NEED_KERNEL_MODULE_ROOT = Optional, if true, install kernel
# modules in root instead of vendor
# NEED_KERNEL_MODULE_SYSTEM = Optional, if true, install kernel
# modules in system instead of vendor
# NEED_KERNEL_MODULE_VENDOR_OVERLAY = Optional, if true, install kernel
# modules in vendor_overlay instead of vendor
#
# TARGET_FORCE_PREBUILT_KERNEL = Optional, use TARGET_PREBUILT_KERNEL even if
# kernel sources are present
#
# TARGET_MERGE_DTBS_WILDCARD = Optional, limits the .dtb files used to generate the
# final DTB image when using QCOM's merge_dtbs script.
