Save pg_stat_statements statistics file into $PGDATA/pg_stat directory at shutdown.
187492b changed pgstat.c so thatthe stats files were saved into $PGDATA/pg_stat directory when the serverwas shutdowned. But it accidentally forgot to change the location ofpg_stat_statements permanent stats file. This commit fixes pg_stat_statementsso that its stats file is also saved into $PGDATA/pg_stat at shutdown.Since this fix changes the file layout, we don't back-patch it to 9.3where this oversight was introduced.
