That's because the code which puts the breakpoint bitmap in the
left fringe explicitly specifies the face (breakpoint-enabled
or breakpoint-disabled) for the bitmap:

             nil (1+ start)
             `(left-fringe breakpoint
                           ,(if enabled

Did you try it?

However, if you really want to do this, you should define a new
white-overlay-arrow bitmap and give it a white face -- then, when you
know overlay is above a breakpoint bitmap, you could explicitly map
overlay-arrow to white-overlay-arrow in fringe-indicator-alist.
