We want to avoid shipping any files generated by depmod (which should
be generated in the postinst) and the 'build' and 'source' symlinks
(which should be installed by the linux-headers package). Since
depmod has generated more and more files over time, we have been
removing all unexpected files under /lib/modules/<kernel-version>,
accidentally including modules.builtin which is *not* generated by
depmod.
Try to solve the problem generally by substituting a dummy depmod
command and then just removing the 'build' and 'source' symlinks.
