The prepare/compile/install targets feel a bit mixed, so it's not
100% clear where this should happen.
But as the `.headers_compile_mark` already triggers various kernel
build targets with a correct kconfig setup, it is a good fit to add
the modules_prepare step (which is recommended to use when preparing
a out-of-three (OOT) module build environment like dkms expects)
there. As we can only copy (= install) the `scripts` directory
afterwards it follows that it needs to be moved afterwards. Moving
installing the `include` directory there is not really necessary but
it feels like a better place than the _prepare_ target and safes a
extra line, so move that over too.
In terms of actual changes to the built header package we get
additionally the, now generated, module.lds file.

Those files are generated by the `if_changed` macro from
scripts/Kbuild.include and are not really useful or interesting for
being shipped in the header packages and other distros (checked
Debian and Ubuntu) do not seem to ship those at all..
So, lets prune them to reduce shipped files dramatically, without
losing, well, anything.
