Move coverage builds prebuilt special case to make

Having this in make has the following advantages
- allows this to be used in other places in make that are sensitive to
  prebuilt selection, e.g. apex boot jars that are present in source but
  not in prebuilt apexes
- collocates the various prebuilt special edge cases
