attribute 'func_timeout' missing

[dustinlacewell]

I've got a project that depends on func_timeout and I get the following error when trying to build:

nix-build default.nix --show-trace
error: while evaluating the attribute 'drvPath' at /nix/store/psgawf6lk8i7s9n4jxsbbr8scv0bmh4a-nixos-20.09pre228622.029a5de0839/nixos/lib/customisation.nix:163:7:

I believe this is fixed by #127.
Please reopen if that's not the case.
