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:

	    (gdb-put-string
	     nil (1+ start)
	     `(left-fringe breakpoint
			   ,(if enabled
				'breakpoint-enabled
			      'breakpoint-disabled))

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.
