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.
Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
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.

Since Ubuntu Eoan the kernel compression was changed from GZIP to
LZ4, due to slightly faster load times vs. a 25% size increase
trade-off (e.g. 5.0 had ~ 8, this one has ~ 12 MB; *but* the initrd
stays roughly the same size, and that one is 5 times bigger anyway)
If we want to keep that is in the stars, but for now correctly
document the build-dependency to LZ4.

The PC speaker (beeper) can only be managed by one module, and there
are two which could do so. The very basic INPUT_PCSPKR, and the more
advanced SND_PCSP which allows it to be used as primitive ALSA
soundcard, which for Proxmox Server projects, and all modern
workstations is not much of use.
As they both were aliased to the "pcspkr" module name, and used the
same internal driver name (being a replacment of the other), one
would get the following error message when both are loaded:
"Error: Driver 'pcspkr' is already registered, aborting..."
in the kernel log. This happens as by default both are tried to get
loaded. We do not want the more complex ALSA one, so disable that.

Allows to mount VFAT devices even if the currently running kernel was
removed before any VFAT, or other FS using the default Native
Language Support module was mounted during the current uptime.
This then could break updating the ESP partitions, which are mounted
with VFAT in a postrm triggered step - so at a time where the current
/lib/modules/... was already removed, and so the NLS could not get
loaded.
While there are a lot of different NLS, our kernel config has:
> CONFIG_FAT_DEFAULT_IOCHARSET="iso8859-1"
So compile that module as built-in.

There where just to much issues with the 4.15 in tree drivers for our
