[PATCH 02/13] qemuxml2argvtest: Resolve resource leaks found by Valgrind

[John Ferlan <jferlan@xxxxxxxxxx>]

Valgrind deterimined that fakeSecretGetValue() was using the secret
value without checking validity.  Returning NULL causes the caller
to emit a message and results in failure.

Additionally commit 'b090aa7d' changes leaked vncSASLdir and vncTLSx509certdir
