The new installer just builds the src tarball that way.  I asked for the
same feature, but it didn't make it into 9.  Deleting all the extra bits
will work for now.  If you are up for it, you can look at patching the
release build process and bsdinstall to restore this feature.  I'm not
sure it would be useful to split out all the top-level src directories as
the old installer did, but having one tarball for the equivalent of the
old 'sbase' + 'ssys' and a second tarball for the rest of the source tree
(so you can do 'none', 'kernel-only' or 'full source') would probably be
a useful thing to implement.
