Exclude backup_manifest file that existed in database, from BASE_BACKUP.

Browse Source 
If there is already a backup_manifest file in the database cluster,
it belongs to the past backup that was used to start this server.
It is not correct for the backup being taken now. So this commit
changes pg_basebackup so that it always skips such backup_manifest
file. The backup_manifest file for the current backup will be injected
separately if users want it.
