build: Use blacklist instead of whitelist for jshint/jscs/jsonlint

* jsonlint now includes docs/, includes/ (api and installer i18n),
  maintenance/, and tests/.
  539 files -> 864 files.
  - Continue to exclude JSDuck artefacts in docs/js/.
  - Continue to exclude vendor/.

* jshint now includes mw-config/ and maintenance/.
  177 files -> 179 files.

* jscs now includes everything jshint includes.
  172 files -> 179 files.
  - The -skip.js files no longer need excluding.

Use the native exclude syntax for jshint and jscs so that other
software and services with JSHint support use these as well.
