[libfuzzer] Enable trace-malloc-unballanced.test on Windows. 

Summary:
Enables trace-malloc-unbalanced.test on Windows, fixing two problems it had with Windows before.
The first fix is specifying python instead of relying on a script's shebang since they can't be used on Windows.
The second fix is making the regex tolerate windows' implementation of the "%p" format string.
