When hosts are using VM separation features, they need qemu
on the target to launch guests (and for other purposes) .. but
they do not want *all* of the build qemu targets. To allow a
more fine grained installation off qemu components, this patch
splits packaging into:
- qemu-<arch>
- qemu-support
- qemu-keymaps
