Fix bufmgr so CHECKPOINT_END_OF_RECOVERY behaves as a shutdown checkpoint.

Recovery code documents clearly that a shutdown checkpoint is executed atend of recovery - a shutdown checkpoint WAL record is written but the buffermanager had been altered to treat end of recovery as a normal checkpoint.This bug exacerbates the bufmgr relpersistence bug.Bug spotted by Andres Freund, patch by me.
