Fix issue where relative links in $PGDATA could be stored in the backup with the wrong path.

Browse Source 
Relative link paths were being combined with the paths of previous links (relative or absolute) due to the $strPath variable being modified in the current iteration rather than simply being passed to the next level of recursion.

This issue did not affect absolute links and relative tablespace links were caught by other checks, though the error was confusing.

Reported by Cynthia Shang.
