I find it a bit confusing that we are including the dart:io sources here, but do
not provide any of the native code. We should probably skip including these
sources.

If we do not have dart:io then including the observatory code is also
unnecessary.

This dart binary will not be usable as it lacks the support to be loading
sources. Should we not drop it for now to avoid confusion?
