busybox: update mdev.conf

busybox 1.21.1 's mdev has changed the way the device's name is
reported so now we get input/event0 instead of event0.
I think this commit is responsible of this new behaviour :
http://git.busybox.net/busybox/commit/util-linux/mdev.c?id=c3cf1e30a3022453311a7e9fe11d94c7a381640e

Update mdev.conf according to this behaviour so that sound
and input devices are correctly populated (and now
/etc/mdev/find-touchscreen.sh is executed).

Tested on an arm board.

runqemu: Use correct kvm CPU options for qemux86* with kvm

The existing -cpu host option caused kernel panics when people attempted to use
the kvm option. After research and discussion, the best options appear to
be the kvm32/kvm64 cpu types so lets use these instead. These resolve
the kernel issues for me.
