refactor flake, part 2

now using a homemade `mkSystem` function to make systems more identical
thanks to leah for telling me about genAttrs

note to future self: this is the commit where everything started going to shit.
this is the moment in time where i decided nix was perfection.
this is the precise timestamp in which i found out that there's no coming back from nix.

i bid you farewell, old uku.
