[ Upstream commit 10f84c2cfb5045e37d78cb5d4c8e8321e06ae18f ]

Currently, the various torture tests sometimes react to an early-boot bug by rebooting. This is almost always counterproductive, needlessly consuming CPU time and bloating the console log. This commit therefore adds the "-no-reboot" argument to qemu so that reboot requests will cause qemu to exit.
