ci: Build parallel port code on supported systems
Build parallel port code on supported systems Unsupported systems are: * Windows operating system * MacOS operating system This means the CI can test * native Linux builds (yes, even for arm systems) Untested at this time are the BSDs. Removes the dysfunctional Windows (since Windows XP) parallel port code, and has the buildsystems fail Windows builds if parallel port builds are requested (HAVE_PARPORT or --enable-parport). https://github.com/avrdudes/avrdude/pull/1874#issuecomment-2275762550
