github actions: use offical UPX, update .editorconfig (#1031)

* Update .editorconfig so my Emacs doesn't add tabs into the YAML files
  anymore

* The UPX version in ubuntu doesn't use the NRV library and seems to be
  a bit buggier. Furthermore, UPX is GPL and they allow an exception
  only if the binary is compressed with the official build. The latter
  is not really a problem, nobody will care, but the worse compression
  and potential crashes are. So just use the official build for Linux.
  Windows was already using it, but to keep it consistent with
  UPX_VERSION we now also download it instead of using Chocolatey.
