analysis_options.yaml for test folder not working

[ruslan-rudenko-solid]

Starting from 0.2.0 version. analysis_options.yaml file inside test folder is ignored by linter.

This could potentially be a fix. Need to test it out thoroughly and submit it to dart_custom_lint if it works OK.

In short -- looks like with recent changes, custom_lint requires .dart_tool/package_config.json to be present alongside each analysis_options.yaml file. This basically limits it to a single analysis_options.yaml file in the root of the package. Nested analysis options are ignored.

The diff below removes the check for .dart_tool presence, making custom_lint parse all available analysis options as context roots, and correctly process them.

EDIT (thx @solid-vovabeloded) we should look for .dart_tool recursively in parent dirs instead of returning true.
