www/php-google-api-php-client: New port

The Google API Client Library enables you to work with Google APIs such
as Google+, Drive, or YouTube on your server. These client libraries are
officially supported by Google. However, the libraries are considered
complete and are in maintenance mode.
This means that we will address critical bugs and security issues but
will not add any new features.
