Add support for the static stack

[dmikusa]

Describe the Enhancement

The static stack is even smaller than tiny. It's designed for using with static binaries like from Go or Rust. It has a different stack id, so we need to add a check for that here.

Motivation

The static stack is a place where folks might want to use a Procfile.
