Fix ADIOS build issues.

I recently tested out building against ADIOS.

Unfortunately, I made a couple of mistakes with setting up the dependencies for an ADIOS-enabled build (it used the non-ADIOS dependencies, so it would not build in parallel sometimes). These commits should correct those oversights.

Additionally, ADIOS 1.6.0 is a bit stricter about naming for variables in files, so this also corrects those (it no longer treats `/<id>` the same as `<id>`).
