I've attached a patch in which I've changed bash and coreutils for 
bash-minimal and coreutils-minimal.

Also, since every package in `inputs` was actually just a build 
dependency, I've moved them all to `native-inputs`.

I've tested `./pre-inst-env guix build tosdr-chromium 
--target=aarch64-linux-gnu`, but since everything is a native input, it 
gives out the exact same derivation.
