You need a scheme engraver to do this, since it must generate a
StanzaNumber for every lyric then discard the mid-line stanza numbers:

\version "2.14"

\relative c' { c2 c \break c c }
\addlyrics{ \set stanza = #"1. " la la la la }
\addlyrics{ \set stanza = #"2. " ho ho ho ho }

\layout {
  \context {
    \Lyrics
    \remove "Stanza_number_engraver"
    \consists #(lambda (ctx)
                 (let ((text #f))
                   `((process-music .
                       ,(lambda (trans)
                          (let ((stanza (ly:context-property ctx 'stanza)))
                            (and (markup? stanza)
                                 (set! text (ly:engraver-make-grob
trans 'StanzaNumber '()))
                                 (set! (ly:grob-property text 'text) stanza)))))
                     (stop-translation-timestep .
                       ,(lambda (trans)
                          (set! text #f))))))
    \override StanzaNumber #'after-line-breaking =
    #(lambda (grob)
       (and (= (ly:item-break-dir (ly:grob-object (ly:grob-parent grob
X) 'left-neighbor))
               CENTER)
            (ly:grob-suicide! grob)))
  }
}
