t/qemu-runlinux: Use multidevs=remaps for 9P setup

Fixes the following warning that started to appear:

    kirr@deca:~/src/wendelin/wendelin.core/t$ ./qemu-runlinux -g  /home/kirr/src/linux/obj-qemu_debug/arch/x86/boot/bzImage /bin/bash
    qemu-system-x86_64: warning: 9p: Multiple devices detected in same VirtFS export, which might lead to file ID collisions and severe misbehaviours on guest! You should either use a separate export for each device shared from host or use virtfs option 'multidevs=remap'!

See for documentation of
multidevs option.
