attractmode - checkout the main repository first, for compatibility with source checking

Previously the location of the sfml-pi repo would be used as it was called first on the RPI,
which would mean an update is always done as the sfml-pi hash would have been stored rather than the
main repository. Ideally we would handle it so if either repository updates, but that requires a fair
amount of additional code as with mupen64plus and it's not work it for this - the sfml-pi code doesn't
change that often and better to just base it on the core code
