Use as a flake input

I tried to use this as a flake input, but due to the inability to pass the system it seems to be an impossible task.

ghcide-nix/nix/sources.nix

Lines 157 to 171 in 521e28d

	{ sourcesFile ? if builtins.pathExists ./sources.json then ./sources.json else null
	, sources ? if isNull sourcesFile then {} else builtins.fromJSON (builtins.readFile sourcesFile)

	, pkgs ? mkPkgs sources system
	}: rec {
	# The sources, i.e. the attribute set of spec name to spec
