Fix example Zephyr build (#333)

On commit 5c7c11e of the tensorflow repo at
tensorflow/lite/micro/tools/make/Makefile:664, MICROLITE_CC_SRCS contains
MICROLITE_CC_KERNEL_SRCS. In the new tflite-micro repo, it does not contain
MICROLITE_CC_KERNEL_SRCS. This commit adds MICROLITE_CC_KERNEL_SRCS to
tensorflow/lite/micro/examples/hello_world/zephyr_riscv/Makefile.inc
so that the generated Zephyr CMakeLists.txt doesn't miss these files.

Similar fix made to corresponding file for magic_wand sample.
