[New Package Request] Create Now CLI for Linux — and if possible for other supported operating system(s)

[x80486]

Since it's close to impossible to install the Zeit's Now CLI via npm install -g now (I get the "defeats the purpose of Nix by polluting the global namespace rhetoric"):

gorre@uplink: ~ $ npm install -g now

...it would be nice to have a package for Zeit's Now CLI.

I'm not sure if people specify the operating system, but I'm not using NixOS. I'm using Linux — specifically Arch. I can actually use pacman but I like the Nix Package Manager!

The now-cli seems to be published as a binary now (if you forgive my pun), it doesn't seem to need node to run. Maybe it could be packaged on it's own?

I might take a crack at it myself later if this seems reasonable?
