build runner: don't incorrectly omit reference traces

It's incorrect to ever set `include_reference_trace` here, because the
compiler has already given or not given reference traces depending on
the `-freference-trace` option propagated to the compiler process by
`std.Build.Step.Compile`.

Perhaps in future we could make the compiler always return the reference
trace when communicating over the compiler protocol; that'd be more
versatile than the current behavior, because the build runner could, for
instance, show a reference trace on-demand without having to even invoke
the compiler. That seems really useful, since the reference trace is
*often* unnecessary noise, but *sometimes* essential. However, we don't
live in that world right now, so passing the option here doesn't make
sense.

Resolves: #23415
