Removed reference to Mongo libraries

When trying to build the Docker image in DockerHub the following error was occurring:

Build failed: ADD failed: stat /var/lib/docker/tmp/docker-builder979354735/install-php-mongo-library.sh: 
no such file or directory

In the hopes of eliminating the error I've removed the Mongo library references since I'm not using it anyway.
