linux-qoriq_4.9: ${KERNEL_PACKAGE_NAME} replaces original key "kernel"

*update RDEPENDS to match kernel naming

The kernel class now sets RDEPENDS_${KERNEL_PACKAGE_NAME}-base so this include
needs to do the same, otherwise bitbake emits a warning and the kernel isn't
removed.

*FILES_${KERNEL_PACKAGE_NAME}-image () replaces original key FILES_kernel-image
