curl: add --skip-existing #13993

With this option, the entire download is skipped if the selected target filename already exists when the operation is about to begin. Also works fine with "globs".

Ref: #11012

This seems to empty the output file, instead of just doing nothing:

$ echo hello > foo.txt
$ cat foo.txt
hello
$ ./src/curl https://google.com -v --skip-existing -o foo.txt
Note: skips transfer, "foo.txt" exists locally
$ cat foo.txt
$

Oh. I'll check it out, that certainly looks wrong.

Yeps, it did wrong - fixed now. I updated test 993 to verify the content of existing file after the transfer to make sure it does not do this anymore.

I also added test 995 to verify the case where the file does not exist before the transfer start.
