Previously, we'd try to put the stdout temp file in the same dir as the target, if that dir exists. Otherwise we'd walk up the directory tree looking for a good place. But this would go wrong if the directory we chose got *deleted* during the run of the .do file. Instead, we switch to an entirely new design: we use mkstemp() to generate a temp file in the standard temp file location (probably /tmp), then open it and immediately delete it, so the .do file can't cause any unexpected behaviour. After the .do file exits, we use our still-open fd to the stdout file to read the content back out. In the old implementation, we also put the $3 in the "adjusted" location that depended whether the target dir already existed, just for consistency. But that was never necessary: we didn't create the $3 file, and if the .do script wants to write to $3, it should create the target dir first anyway. So change it to *always* use a $3 temp filename in the target dir, which is much simpler and so has fewer edge cases. Add t/202-del/deltest4 with some tests for all these edge cases.
