Refactor r452431, because this should not be fatal to starting

the server if it's horribly broken.  The alternative of returing
'rc' in this case would be to open /dev/null as the error stream
for this generation of the server; and even more useless result.

Also the parent-file was never necessary; we can pass only the
child handle using apr_procattr_child_err_set() and have no extra
file to clean up afterwards.
