undo-files: cleanup legacy files when applicable

The "journal" code is much more compact in 6.4, and so is the "undo" files as a
result. However the previous version were much noisier, so let us cleanup undo
files from older version too.

  $ cat >> $HGRCPATH <<EOF
  > [censor]
  > policy=ignore
  > EOF

  $ mkdir r
  $ cd r
  $ hg init
  $ echo secret > target
  $ hg commit -Am "secret"
  adding target
  $ touch bystander
  $ hg commit -Am "innocent"
  adding bystander
  $ echo erased-secret > target
  $ hg commit -m "erased secret"
  $ hg censor target --config extensions.censor= -r ".^^"
  $ hg update ".^"
