selftests/kexec: Add x86_64 selftest for kexec-jump and exception handling
Add a self test which exercises both the kexec-jump facility, and the
kexec exception handling.
Invoke a trivial payload which just does an int3 and returns,
flip-flopping its entry point for the next invocation between two
implementations of the same thing.
