christos 328064d112 Redo the previous change so that we can ignore access errors from find,
but also tell when writing to the output file failed, by using a pipeline
to cat. While here change `` to $(). Otherwise this would always fail
since it is ran as nobody and therefore it cannot access some files. Reported
by smb.
