    kernel: Fix QA buildpaths warning for kernel modules
    
    CFLAGS is unset during kernel_do_compile and thus the default build
    path substitutions in DEBUG_PREFIX_MAP are missing.
    
    To enhance reproducible build for kernel modules, such as lttng-modules
    and cryptodev-module, this patch appends them, plus substitution of
    STAGING_KERNEL_DIR, to KERNEL_CC.
