Bug#521515: linux-headers-2.6.29-1-amd64: please restore symlinks into -common

We may also be able to fix the OpenAFS build system if this was an
intentional architecture change to solve some problem, although as Aaron
mentions OpenAFS has kernel build support for eight or nine different
UNIXes and a compatibility layer which makes this trickier.

What's the intended use of the new layout in these packages?  Are modules
expected to provide a search path for include files rather than assuming
headers are in one unified location?
