With the development version, you can do:

\override TupletBracket #'X-positions =
#(lambda (grob)
  (let* ((right (ly:spanner-bound grob RIGHT))
         (bd (ly:item-break-dir right))
         (xshift (if (= bd -1) -0.5 0.0)))
    (coord-translate (ly:tuplet-bracket::calc-x-positions grob)
                     `(0 . ,xshift))))
