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.

-
-A Rust library for retrieving random data from (operating) system source. It is
-assumed that system always provides high-quality cryptographically secure random
-data, ideally backed by hardware entropy sources. This crate derives its name
-from Linux's `getrandom` function, but is cross platform, roughly supporting
-the same set of platforms as Rust's `std` lib.
-
-This is a low-level API. Most users should prefer using high-level random-number
-library like [`rand`].
-
-[`rand`]: https://crates.io/crates/rand
-
-## Usage
-
-Add this to your `Cargo.toml`:
-
-```toml
-[dependencies]
-getrandom = "0.1"
-```
-
-Then invoke the `getrandom` function:
-
-```rust
-fn get_random_buf() -> Result<[u8; 32], getrandom::Error> {
-    let mut buf = [0u8; 32];
-    getrandom::getrandom(&mut buf)?;
-    Ok(buf)
-}
-```
-
-## Features
-
-This library is `no_std` for every supported target. However, getting randomness
-usually requires calling some external system API. This means most platforms
-will require linking against system libraries (i.e. `libc` for Unix,
-`Advapi32.dll` for Windows, Security framework on iOS, etc...).
-
-The `log` library is supported as an optional dependency. If enabled, error
-reporting will be improved on some platforms.
-
-For the `wasm32-unknown-unknown` target, one of the following features should be
-enabled:
-
--   [`wasm-bindgen`](https://crates.io/crates/wasm_bindgen)
--   [`stdweb`](https://crates.io/crates/stdweb)
-
-By default, compiling `getrandom` for an unsupported target will result in
-a compilation error. If you want to build an application which uses `getrandom`
-for such target, you can either:
-- Use [`[replace]`][replace] or [`[patch]`][patch] section in your `Cargo.toml`
-to switch to a custom implementation with a support of your target.
-- Enable the `dummy` feature to have getrandom use an implementation that always
-fails at run-time on unsupported targets.
