Include column name for v4 raw fwd index build failure

[itschrispeck]

It's useful to know which column caused the build failure so it may be addressed more quickly by operators. Currently users are left to guess which column caused the exception.

_dataBuffer.getFile() output is in the format: column_name.sv.raw.fwd
