added lr-fbalpha2018 module

upstream fbalpha moved to github, so libretro deprecated the old fbalpha repository and renamed it to fbalpha2018.
lr-fbalpha is now a fork of the upstream development and will be more up to date, but will require more frequent
romset changes - see https://retropie.org.uk/forum/topic/19741/new-fb-alpha-libretro-pre-v0-2-97-44
