searchview: fix mbox.gz downloads for lynx users

Unlike w3m and links, the lynx browser seems to require a `name'
attribute for `<input type=submit>' elements.  Maybe some other
browsers do, too.  The `name' attribute for submit elements
doesn't seem to cause any harm for w3m or links, users, either;
despite not (AFAIK) being part of historical or current HTML
specs.
