config: x86: stop pretending to be an Lguest guest 

Ever since v2.6.36 there's a conflict between OLPC support and Lguest
guest support: a kernel image can't both support booting OLPC x86
hardware and booting as an Lguest guest. Booting a kernel image that
tries to do both as an Lguest guest will fail with
    lguest: Reinjecting trap 13 for fault at 0x1000062: Invalid argument

This means that people wanting to boot an Lguest guest on 32 bits x86
needed to build their own kernel image without OLPC support since, it
seems, Fedora 15. So let's stop pretending to support being an Lguest
guest. People wanting to have that will now not only have to disable
CONFIG_OLPC but also enable CONFIG_LGUEST_GUEST.

(A second order effect is that both CONFIG_VIRTIO and
CONFIG_VIRTIO_CONSOLE will change from 'y' to 'm' in our builds.
Assuming a sane build system no one should notice. We'll see.)
