rG3c0686082df8: bhyve: Eliminate exit status magic numbers

Summary

bhyve's exit status codes indicate how the VM was terminated.
Unfortunately, their meaning within the source code is somewhat
unclear since they are only used as magic numbers.

Fix this by defining exit status macros and using them to replace
the magic numbers in exit(3) function calls.

usr.sbin/bhyve/bhyverun.h
37	Maybe comments here and in bhyve.8 mentioning that this list also exists in the other one?

Address @emaste 's comment.

usr.sbin/bhyve/bhyverun.h
37	Thanks for the suggestion, I've added a reference to the manpage here. I don't think it makes sense to reference the `bhyverun.h` list in the manpage.
