Alyssa Ross 5fc7992364 rust-bindgen: use a better drv name for fakeRustup
I saw a derivation called "rustup" building and was concerned why
rust-bindgen would depend on rustup.  If it had been called
"fake-rustup", I wouldn't have had to check the package source to see
what was going on. :)

longDescription = ''
Bindgen takes a c or c++ header file and turns them into
rust ffi declarations.
As with most compiler related software, this will only work
inside a nix-shell with the required libraries as buildInputs.
