run_processes_parallel: rename parameters for the callbacks

The refs code has a similar pattern of passing around 'struct strbuf *err', which is strictly used for error reporting. This is not the case here, as the strbuf is used to accumulate all the output (whether it is error or not) for the user. Rename it to 'out'.
