Fix resource leak in initdb -X option

When creating the symlink for the xlog directory, free the string
which stores the link location.  Not really an issue but it doesn't
hurt to be good about this- prior cleanups have fixed similar
issues.

Leak found by the Coverity scanner.

Not back-patching as I don't see it being worth the code churn.
