scripts/runqemu-internal: use -cpu core2duo for qemux86-64
Now that the tune for qemux86-64 changed to core2-64 we need to
tell the emulator to use a proper CPU model. With the default setting
of qemu64 we'll get things like:
root@qemux86-64:~# smart --help
traps: python[758] trap invalid opcode ip:
7f2af01f6be7 sp:
7fff49466ef0 error:0 in strop.so[
7f2af01f5000+6000]
Illegal instruction
If the tune for qemux86 changes, that needs to be updated too.
