doc: Clarify CHECKPOINT handling of unlogged buffers

The CHECKPOINT reference page still described checkpoints as flushing
all data files, which could be misleading as it depends on the value
of FLUSH_UNLOGGED option.  Update the description to make it clearer
that only data files of permanent relations are flushed by default.
