hvm: Allow triple fault to imply crash rather than reboot
While the triple fault action on native hardware will result in a system
reset, any modern operating system can and will make use of less violent
reboot methods. As a result, the most likely cause of a triple fault is a
fatal software bug.
This patch allows the toolstack to indicate that a triple fault should mean a
crash rather than a reboot. The default of reboot still remains the same.
