Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"

message that we had back in apache-1.3 and is still scattered throughout
our docs.

Unfortunately, when mod_suexec is a DSO we're going to get this thing
twice in our logs. I believe as a side effect of the load-unload-load
cycles of our DSOs we're losing the static data segment, which is where
the "didn't we already report this" flag lives.
