    tools: use $(PYTHON) to call cppcheck tools
    
    When calling python tools to convert misra documentation or merge
    cppcheck xml files, use $(PYTHON).
    While there fix misra document conversion script to be executable.
    
    Fixes: 57caa5375321 ("xen: Add MISRA support to cppcheck make rule")
    Fixes: 43aa3f6e72d3 ("xen/build: Add cppcheck and cppcheck-html make rules")
