refactor: remove cli code wrapper for karma 0.10

This commit removes a cli wrapper that supported karma 0.10. This is no
longer needed and we can just call the run method directly from the
Karma package since all the command parsing is done there.

-// This wrapper only resolves which instance of Karma should be run.
-// All the logic is in the main Karma module.
-// The resolving algorithm checks (in this order):
-//   - a local module (using `require`, so it will traverse up, looking for `node_modules/karma`),
-//   - a siblink module to karma-cli (that loads the global karma, when using NVM),
-//   - a global module (NODE_PATH)

-// TODO(vojta): remove once we don't care about Karma 0.10
