[lld/mac] add test coverage for -sectcreate and -order_file with --reproduce

[thakis]

Summary

Would've caught the (since fixed) regression in D97610.

No behavior change.

Completely legit 👍

Hi, the file you create here sectdata.txt is being flagged as a virus by Windows Defender in our internal bot causing the file to be automatically deleted and the test to fail. Is there a reason why you need to use that particular string for the file? Can something else be used that won't trigger the antivirus?

[int3]

😂yeah I'm pretty sure @thakis only intended that to be a sort of "lorem ipsum" placeholder text. We can remove it for sure: D101402

Huh, I thought virus scanners are only supposed to warn on this if it's at offset 0. Yes, any string is fine. Sorry about this breaking your bots.
