[MOV] test_pylint, test_lint: add es-check linter

Because Odoo still supports Android Kitkat and Internet Explorer, ES5 is
the highest ECMAScript allowed version.

This commit adds a new test that parses each javascript file found in
addons. The test fails if unsupported js code is found.  As ES6 is
allowed during tests, the files under a path that contains 'static/test'
are just skipped.

This test uses the es-check tool
(https://www.npmjs.com/package/es-check).

If the es-check tool cannot be found, the test is simply skipped.

Also the test_pylint module is renamed to a more generic name test_lint,
that way, every linter test can find a shelter  here.
