[status_file] Status file linting should not check for non-existing files when given input on stdin

Given input on stdin it has no path to resolve the relative paths that
exists in a status file from. It will thus complain about almost all
lines which is not ideal.
This CL changes it so it doesn't check for it when given data on stdin.
This also means that - because there are no old errors on that account -
if there are such errors now you will be forced to fix it.
The current errors in the status files I could find have also been
fixed.

This should for instance have flaggen when I in
https://dart-review.googlesource.com/c/sdk/+/400320 updated the
pkg.status file but forgot to actually rename the underlying file
(as fixed in https://dart-review.googlesource.com/c/sdk/+/400560).
Technically I suppose it _did_ flag it, but there were also hundreds of
lines of false positives caused by the old status file been given at
stdin to check if there were existing errors - which there then was, thus not forcing me to do anything.

Logical follow-up to https://dart-review.googlesource.com/c/sdk/+/370886

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
