SI-7790 No ScriptEngine in 2.10 build

The service entry was inadvertendly added in
`e3b5e0ba40447970d621cfeed5cc1770df69884f`,
"Sanity for build.xml: exscriptus&positus delendus est,"
which is ant latin for: "Reduced copy/pasting to the best
of my antabilities."

With that degree of hubris, it was inevitable that the
commit introduced a copy/paste bug.  What is the Attic
Greek for copy/paste?

I'm pretty sure that in fifth century Athens they would
just pound one inscription to rubble using a bigger
inscription. They had slaves for that kind of work.
You never hear about Socrates tweaking the build script.
That's the reason he never wrote anything down.
