Fix type for abs() calls in devel/obby

During the exp-run in bug 208158, it was found that devel/obby gives errors with libc++ 3.8.0 [1]:

colour.cpp:50:9: error: call to 'abs' is ambiguous
        return abs(m_red - colour.m_red) +
               ^~~

This is because abs() is being called with unsigned arguments.  Fix this by casting the arguments to the appropriate signed type.
