WIP: build: initial linux x86_64 support using nix

[bennyandresen]

it basically builds without error. Both the shared graal library "LibScimacs" and the Rust library "scimacs". It can't be loaded for a reason I don't yet understand.

Module could not be opened: "/home/benny/Code/Playground/scimacs/scimacs.so", "/home/benny/Code/Playground/scimacs/scimacs.so: undefined symbol: graal_create_isolate"

Full results:
