Add support for building within a kernel package
 

I don't want to waste your time, but there are enough changes here
that a split patchset would improve reviewing.

Shouldn't depmod be passed a System.map here? My experience with d-i's
build system's use of depmod has taught me to always provide a
System.map to it when the running kernel may differ from the kernel
being prepared.
