kernel: Fix QA buildpaths warning for kernel modules

Browse Source 
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.
