QEMU: Terminated hang/fail

Note: same silent-hang signature as snv_134/2048 x snv_134-ai-iso (see
snv_134-2048__disk.s10hw2.txt for the PASS case at this same build/mem
size against a different image) -- consistent with the diagnosed
QEMU-side gap in hyperprivileged-self-call MMU_MAP_ADDR (ta 0x83)
handling, not re-verified via register/trap dump for this specific run.
