[Build] Skip early-* on non-darwin hosts

[bnbarham]

These builds do not work outside of darwin currently. Rather than adding the skip to all the necessary build presets, just disable in the product instead.

@swift-ci please test

import sys is needed in the Python files, otherwise good.

Yeah, just saw the failure and re-pushed.

@swift-ci please smoke test

[finagolfin]

Looks like three build script tests explicitly look to see if the early swift driver output is there, so they will need to be modified too.

@swift-ci please smoke test Linux platform

[finagolfin]

Why was that linux smoke test failing? I didn't find that module.map error from the CI anywhere in the compiler source.

[bnbarham]

It's in LLVM (swiftlang/llvm-project#7307). Seems that we don't run SwiftPM tests there.

Ah, makes sense, as that pull you reverted was just merged a couple hours ago, whereas I was looking in an LLVM checkout from this morning.

Yeah, status job wasn't up to it yet either which initially confused me 😅
