I used to use alignGrob for this. (See the LSR). But later I wrote this 
based on that:

endbar = {
  \overrideProperty #"Staff.BarLine" #'after-line-breaking
  #(lambda (grob)
     (let* ((sys (ly:grob-system grob))
            (staff (ly:grob-object grob 'staff-symbol))
            (half-thickness (/ (ly:staff-symbol-line-thickness staff) 2))
            (cur-x (cdr (ly:grob-extent grob sys X)))
            (new-x (cdr (ly:grob-extent staff sys X)))
            (xoff (+ half-thickness (- new-x cur-x))))
         (ly:grob-set-property! grob 'extra-offset (cons xoff 0))))
}
