How about if "make install" unloads uprobes.ko?

For that matter, "make install" could attempt to build uprobes.ko, to help
prevent the situation where a stapdev or stapusr user can't run his script until
root builds uprobes.ko for him.  (It would have to be tolerant of the case where
there's already a kernel-built version of uprobes.)

Another thing we could do is add a script to /etc/init.d to (re)build
uprobes.ko, thus keeping it in sync with the running kernel.
