Update old-style copyright headers

Updates old-style copyright headers to the new style, by removing "All
rights reserved." Also inserts "The" before "PDFium Authors", which is
required by both styles.

Mechanically generated by this command:
  PATTERN='Copyright \([0-9]\+\) \(The \)\?PDFium Authors. All rights reserved.'
  git grep -l "$PATTERN" \
  | xargs sed "s/$PATTERN/Copyright \1 The PDFium Authors/" -i''
