Define dummy use/vmguest/vbox/dri use/vmguest/vmware/dri targets
for non-x86 architecures to avoid the problem.

This is useful for images with wayland only.

virtualbox use vmsvga video adapter by default.

qemu-guest-agnet is now available in sisyphus_riscv64.

xorg-dri-virtio not available for p10 armh.

The list must not contain empty lines.
Otherwise, all modules are added to the initrd.
Fix commit 3e7b5828

xorg-dri-virtio was added via REGEXP to work around the package
missing issue on p9. But it didn't work.

xorg-dri-virtio is a separate package in Mesa 21.1.
But in p9 Mesa 21.0, so the package is added to regexp.

Already in the mainline linux kernel >= 5.10.

There are a few more targets used for Workstation
and Simply images that are rather better plugged
here than patched there.

(still preferring 80-char wide xterm for proofreading)

It's actually sisyphus jeos image that needed this:
open-vm-tools got installed and then removed just
before the final reboot (unlike p8 jeos); not clear
what exactly caused this as subsequent installation
only pulled in libdnet and libicu56, neither of which
were excplicitly removed during cleanup.

Let's make the image a bit leaner until someone asks
for VMware support there.

+vmguest should work everywhere it can at all either;
it's most advanced on x86_64 in terms of hypervisors
available; still aarch64 has kvm too.

'twas somewhat incomplete otherwise,
and these two packages are pretty tiny.

Note that +vmguest is affected too.

xorg-drv-vmmouse should accompany xorg-drv-vmware.

This might be an overreaction but let's handle
non-x86 virtualization on per-case basis.

Thanks sbolshakov@ for the notice.

This has long been a TODO item but an elegant solution
just didn't come until the night before starterkits...
some services (mostly those operating on real hardware)
do not fit virtual environments at all, won't even start.

These are aimed to test the modules.d/ and auto-pickup
implementation as well as to present an example.

At least 50-net might change (or just get renamed to avoid
auto-pickup) some day as the "net" feature's meaning is
to provide networking upon bootup and these modules are
only needed within stage1 if we're going to netboot;
and that's quite different thing.

armh-cubox bits are prone to get renamed/generalized too
since e.g. ArmadaXP based server images are going to need
this as well.

use/vmguest/vbox/base used to pull in DRM modules
which are required for vboxvideo but useless without
xorg bits; and all of these aren't needed in jeos.

Things might break, doublecheck please.
