Add KTR_EMUL to indicate a switch between syscall emulations.
...
Currently this record is emitted only on exec. Maybe it should
be emitted on ktrace() attach too.

a program being exec'd *must* cause *some* exec commands to be invoked;
...
if it doesn't there's a problem in the kernel, because a program
with no exec commands run will have no address space except the stack,
and i don't think it's valid to have a "run from stack only" exec type,
so panic. if need for that case comes up later, it can be changed...
