Remove vendored dependencies

While it appears that by now we actually can get successful builds
without Cargo insisting on Internet access by virtue of using the
--frozen flag, maintaining vendored dependencies is somewhat of a pain
point. This state will also get worse with upcoming changes that replace
argparse in favor of structopt and pull in a slew of new dependencies by
doing so. Then there is also the repository structure aspect, which is
non-standard due to the way we vendor dependencies and a potential
source of confusion.
In order to fix these problems, this change removes all the vendored
dependencies we have.

Delete subrepo argparse/:argparse
Delete subrepo base32/:base32
Delete subrepo cc/:cc
Delete subrepo cfg-if/:cfg-if
Delete subrepo getrandom/:getrandom
Delete subrepo lazy-static/:lazy-static
Delete subrepo libc/:libc
Delete subrepo nitrokey-sys/:nitrokey-sys
Delete subrepo nitrokey/:nitrokey
Delete subrepo rand/:rand

-//! A macro for defining `#[cfg]` if-else statements.
-//!
-//! The macro provided by this crate, `cfg_if`, is similar to the `if/elif` C
-//! preprocessor macro by allowing definition of a cascade of `#[cfg]` cases,
-//! emitting the implementation which matches first.
-//!
-//! This allows you to conveniently provide a long list `#[cfg]`'d blocks of code
-//! without having to rewrite each clause multiple times.
-//!
-//! # Example
-//!
-//! ```
-//! cfg_if::cfg_if! {
-//!     if #[cfg(unix)] {
-//!         fn foo() { /* unix specific functionality */ }
-//!     } else if #[cfg(target_pointer_width = "32")] {
