Title: Use RbConfig instead of Config.

As of Ruby 2.2.0, Config no longer exists. Attempting to install the mysqlplus gem produces the following error:

```
extconf.rb:59:in `

': uninitialized constant Config (NameError)

extconf failed, exit code 1
```

This commit makes extconf.rb use RbConfig instead of Config.
