Workaround 'condition appendToFile is always false' cppcheck false positive

* misc.c [(MSWIN32 && !CONSOLE_LOG || MSWINCE) && !MSWINRT_FLAVOR
&& NO_GETENV_WIN32 && CPPCHECK] (GC_CreateLogFile): Define appendToFile
as macro (to FALSE) instead of a local variable; undefine appendToFile
at the function.
