duckstation: preset an extra options, add license link

Set the Memcard 1 save as "Save Ram (libretro .srm)" instead of the native "<game>_1.mcd" file. Should make easier consistent with other libretro cores behavior.

License link updated, taken from https://github.com/stenzek/duckstation#libretro-core.
