[Fuzzer][Test] Use %python substitution for trace-malloc-unbalanced.test

Browse Source 
This test was found to fail for some of our downstream builds, on
computers where python was not on the default $PATH. Therefore
add a %python substitution to use sys.executable, based on similar
solutions for python calls in tests elsewhere in LLVM.
