kernel-devsrc: Handle ppc crtsaves.o explictly for now

Resolve kernel module build failures for qemuppc by including crtsaves.o.

I'm not particularly happy to be doing this, it should perhaps be contained
in the kernel-dev package. Until the overlap between kernel-devsrc and
kernel-dev is resolved, this at least removed the regressions.
