Myles Borins 1fd69872e6 test: add common.skipIfEslintMissing
We've added a number of tests that hook into ESLint which can error
when running the test suite with the distributed tarball. This PR
adds a new test helper `common.skipIfEslintMissing` and will skip
remaining tests in a file when `ESLint` is not available at
`tools/node_modules/eslint`
