Fix overrides files not work

[fyangstudio]

• Support add extends and plugins config.

• Fix overrides files not work, like:

  const { getESLintConfig } = require('@iceworks/spec');
  
  module.exports = getESLintConfig('react-ts', {
  overrides: [
    {
      files: ['**/src/apis/**'],
      rules: {
        'react-hooks/rules-of-hooks': 0,
      },
    },
  ]
  });

  Because cwd is not current project path.
