Input boolean arguments might be being ignored/git submodules

[SomeoneSerge]

Flake inputs since recently support boolean arguments, including submodules = true for git inputs, which are supposed to trigger recursive checkout.

It seems, however, that flake-compat ignores those arguments:

• Flake: https://github.com/SomeoneSerge/triton.nix/blob/f1ed98b8ebad142c10032243e3a50c94dc90ffb5/flake.nix#L9
• nix build -L succeeds to check out microsoft/onnxruntime` recursively (paths in https://github.com/microsoft/onnxruntime/tree/master/cmake/external are available in sources)

• ./build-compat.nix fails with

Hi @SomeoneSerge, I ran into this too - did you find a workaround?

[SomeoneSerge]

Hello @charlesbaynham, I actually don't remember when have I last run into this problem (or the need to use flake inputs with submodules). Lately, I've been using the new builtins.getFlake instead of flake-compat, because I more often needed "shell.nix" for impure evaluation, rather than for handling flake-less installations of Nix

I haven't tested your PR yet, but I presume it would fix the issue
