[Toybox] Fix ftpget tool get command exit with error code 1

[Hongsheng Peng]

Hi Rob,


We work in embedded systems and primarily use `ftpget` to retrieve resources from the server side. 
While FTP may pose security risks, meeting client-side requirements is currently adequate for our needs.
However, having server-side functionality would still be beneficial, as it could prove useful for the debug purpose.



Thanks.
Best regards
Hongsheng Peng

Speaking of which, now that an actual ftp user has shown up: should I
add an ftp server to toybox?

The reason I didn't add an ftp server to toybox already is that ftp
seems to be generally deprecated:

https://bugs.documentfoundation.org/show_bug.cgi?id=146386

But if there are still users out there, ftp is an easy way to move files
between VMs within a LAN, and having clients without a server is a bit
awkward. Right now ftpget and ftpput can't talk to each other, which is
kinda sad, and even if they could ftpget -l needs an actual server to
list files...

(There's also tftp/tftpd in pending, but that's not really designed to
upload stuff, can't list files, is UDP based... A lot of times I build
dropbear and do scp/ssh but I'm not currently planning to build those
into toybox (out of scope, dropbear works fine.)
