Remove gstreamer-plugins-good1.0-dev from the list of Debian dependencies (#44)

- While building Servo on my Debian system, I encountered the following error:

```Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package libgstreamer-plugins-good1.0-dev
E: Couldn't find any package by glob 'libgstreamer-plugins-good1.0-dev'
```
- The build completed successfully without the need to install `libgstreamer-plugins-good1.0-dev`. 

As a result, this dependency has been removed from the Debian section of the configuration. However, a note has been added advising users of Ubuntu-based systems to install it if necessary.
