    Remove stray trailing "," from DAP breakpoint.py
    
    The buildbot pointed out that the last DAP series I checked in had an
    issue.  Looking into it, it seems there is a stray trailing "," in
    breakpoint.py.  This patch removes it.
    
    This seems to point out a test suite deficiency.  I will look into
    fixing that.
