buildkernel: Save unstripped modules for debugging
Currently, the build script installs the modules by stripping off
the symbol information, which further then gets placed on the target.
However, this symbol information is really useful for performing
postmortem analysis. Hence, install a separate copy of unstripped
modules for this purpose.
