getSdkPath does not return correct path when run via flutter_tester

[shyndman]

Hi there,

My Flutter application uses the analyzer package, and I'm finding that after a upgrade, our tests are now failing.

It looks like getSdkPath wasn't designed to accommodate a Platform.resolvedExecutable of flutter_tester (which lives under bin/cache/artifacts/engine/{platform}/flutter_tester

I'm running analyzer 0.39.17, and cli_util 0.2.0.

Here's the exception:

FileSystemException(path=/Users/shyndman/work-code/flutter/bin/cache/artifacts/engine/version; message=Cannot open file)
  package:analyzer/file_system/physical_file_system.dart 194:7               _PhysicalFile.readAsStringSync

  package:analyzer/src/dart/analysis/analysis_context_collection.dart 54:36  new AnalysisContextCollectionImpl

Any suggestions?

I have upgraded to the latest analyzer (0.40.4), and this is still the case. I am using a dependency override pointing to a fork (referenced above) to sidestep the issue for now.
