Fix some documentation in pg_rewind

A confusion which comes a lot from users is that it is necessary to
issue a checkpoint on a freshly-promoted standby so as its control file
has up-to-date timeline information which is used by pg_rewind to
validate the operation. Let's document that properly. This is
back-patched down to 9.5 where pg_rewind has been introduced.
