Make recovery rename tablespace_map to *.old if backup_label is not present.
If tablespace_map file is present without backup_label file, there is
no use of such file. There is no harm in retaining it, but it is better
to get rid of the map file so that we don't have any redundant file
in data directory and it will avoid any sort of confusion. It seems
prudent though to just rename the file out of the way rather than
delete it completely, also we ignore any error that occurs in rename
operation as even if map file is present without backup_label file,
it is harmless.
Back-patch to 9.5 where tablespace_map file was introduced.
