curl: better error message when -O fails to get a good name
Due to how this currently works internally, it needs a working initial
file name to store contents in, so it may still fail even with -J is
used (and thus accepting a name from content-disposition:) if the file
name part of the URL isn't "good enough".
Fixes #7628
Closes #7635
