Describe the bug
The LUA_PATH set by luajit's setup hook does not include the default value ?;?.lua (documented here), so relative imports from the current directory do not work.
To Reproduce
Create two files:
==> a.lua <==
print(require('b'))
==> b.lua <==
return "hi!"~ $ nix-shell -p luajit
[nix-shell:~]$ which luajit
/nix/store/bafy33kb1drwgcdr031vhjl84ls0sni5-luajit-2.1.0-2020-12-28/bin/luajit
[nix-shell:~]$ echo $LUA_PATH
/nix/store/bafy33kb1drwgcdr031vhjl84ls0sni5-luajit-2.1.0-2020-12-28/lib/lua/5.1/?.lua;/nix/store/bafy33kb1drwgcdr031vhjl84ls0sni5-luajit-2.1.0-2020-12-28/share/lua/5.1/?.lua;/nix/store/bafy33kb1drwgcdr031vhjl84ls0sni5-luajit-2.1.0-2020-12-28/share/lua/5.1/?/init.lua;/nix/store/bafy33kb1drwgcdr031vhjl84ls0sni5-luajit-2.1.0-2020-12-28/lib/lua/5.1/?/init.lua
[nix-shell:~]$ luajit a.lua

stack traceback:
[C]: in function 'require'
a.lua:1: in main chunk
[C]: at 0x004062c0
Expected behavior
From a non-nixos system (Arch):
~ $ which luajit
/usr/bin/luajit
~ $ echo $LUA_PATH
# unset
~ $ luajit a.lua
hi
Additional context
For some reason, nix-shell -p luajit sets a LUA_PATH but nix-shell -p lua does not. I don't really understand that.
