[PATCHv20 07/12] run_processes_parallel: rename parameters for the callbacks

[Stefan Beller <sbeller@google.com>]

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'.
