test: invoke scale-test with the interpreter
test: invoke scale-test with the interpreter

The scale-test utility is a python script which was relying on the
shebang to invoke the interpreter.  However, not all targets support
such an invocation mechanism (i.e. Windows doesn't support this).
Explicitly invoke the interpreter to ensure that the tool is executed
properly.
