[SeaBIOS] Download URLs changed

[Paolo Bonzini]

Hi,

it looks like at some point the download URLs for SeaBIOS changed from
https://code.coreboot.org/p/seabios/downloads/get/seabios-X.Y.Z.tar.gz
to https://code.coreboot.org/p/seabios/downloads/seabios-X.Y.Z.tar.gz.

Would it be possible to add a redirect or symlink from the old files, so
as not to break places (such as distribution packages) that have the old
URL in it?

Thanks,

Paolo
