Doc: Redesign default config file

The old one does not work with 2.0.x.

/*
* This is an example configuration file

# Yes, even shell-like comments work...
# This is a basic configuration file, which contains boilerplate options and
# some basic examples. It allows the BIRD daemon to start but will not cause
# anything else to happen.

# Please refer to the BIRD User's Guide documentation, which is also available
# online at http://bird.network.cz/ in HTML format, for more information on
# configuring BIRD and adding routing protocols.
