bitbake: fetch2/wget: Check downloaded file isn't zero size
I can't think of a reason we'd download zero sized files however there are reasons zero length files can accidently make it onto source mirrors. This check allows us to ignore the broken files and switch to another mirror rather than fail with odd checksum failures.
