I think this is likely too fragile, what will happen when the package
gets bumped to a newer version?

I think we need to store a local copy in osstest and install from
there instead of trying to fetch from the upstream Debian mirror.

I guess we could use something similar to DebianExtraPackages?

DebianExtraPackages_build_$arch_$suite nasm_2.15.05-1_$ho->{Arch}.deb

And fetch those using the some_extradebs method.

Thanks, Roger.
