release-post.js script should ignore 32-bit binaries for intel and sunos

[rvagg]

I'd fix this but I'm currently doing releases and am likely to be too exhausted at the end to get around to this.

./scripts/release-post.js needs to not put "Coming soon" for 32-bit binaries for Linux x86 or "sunos" x86 for Node 10+, they're deprecated. But it should still do it for 6 & 8. I think the best way might be to put metadata in scripts/helpers/downloads.js to indicate this and filter them out when we're doing a v10 release.

Well, this issue is fixed and landed here: f0818db

So I closed this and for any other problems, please feel free to re-open.
Thanks anyway!
