Fix issues in gpinitstandby tinc test.

*  Add PG_BASEBACKUP_FIXME:if there are new tablespaces, gpinitstandby fails.
   pg_basebackup can't copy tablespace data to standby, besause the tablespace
   directory is not empty on standby.
*  Check standby tablespace directory.
*  Replace function cleanupFilespaces with function cleanup_tablespace.
