eb_ebb: Move eb_ebb lib from sysless to eurobot/src tree

Note by Michal: It seems that nobody elese uses this library now and it is
easier for us when this library lives in repository, which can be
modified by Eurobot team members.

Note 2: The patch did not apply cleanly, so I simply deleted the eb_ebb
directory.
