license function searches for Dart SDK license in wrong place when Homebrew'd

[srawlins]

I am assuming this is specific to Homebrew...

When Dart is installed with Homebrew, and running the pkg-npm-dev grinder task, I get the following crash:

pkg-npm-dev
  writing build/npm/package.json
  copying build/abc.dart.js to build/npm

FileSystemException: Cannot open file, path = '/usr/local/Cellar/dart/2.7.1/libexec/LICENSE' (OS Error: No such file or directory, errno = 2)

Here are the various files in that Homebrew installation:

Can confirm, I also have this issue
Also installed via homebrew

It looks like this is due to Homebrew unpacking the Dart SDK in a non-standard way by putting the LICENSE file one directory up instead of in the main SDK directory.
