Build xinetd challenges

[jomagalo]

Hello again,
To compile the xinetd challenges I do the following steps:

1. sudo docker-compose build && sudo docker-compose up -d
2. sudo python3 ./build.py -c nmap

After this I see that the files are copied to the build -> xinetd, src and xinetd.d folder.

I do the scan with nmap to the exact port of the nmap challenge. I don't know if I forgot any step. I can't find a way to get the invalid syntax error away (sitecustomize.py, line 1)
