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 random number generator that retrieves randomness straight from the
-operating system.
-
-**This crate is deprecated:** `OsRng` is available in `rand_core` since version 0.5.1.
-
-This crate provides `OsRng` as a shim around
-[getrandom](https://crates.io/crates/getrandom)
-implementing `RngCore` from [rand_core](https://crates.io/crates/rand_core).
-
-Note: the `rand` crate provides an equivalent `OsRng`; the two implementations
-are equivalent, though distinct types.

-/// A random number generator that retrieves randomness from from the
-/// operating system.
-///
-/// This is a zero-sized struct. It can be freely constructed with `OsRng`.
-///
-/// The implementation is provided by the [getrandom] crate. Refer to
-/// [getrandom] documentation for details.
-///
-/// # Blocking and error handling
-///
-/// It is possible that when used during early boot the first call to `OsRng`
-/// will block until the system's RNG is initialised. It is also possible
-/// (though highly unlikely) for `OsRng` to fail on some platforms, most
-/// likely due to system mis-configuration.
-///
-/// After the first successful call, it is highly unlikely that failures or
-/// significant delays will occur (although performance should be expected to
-/// be much slower than a user-space PRNG).
-///
-/// # Usage example
-/// ```
-/// #![allow(deprecated)]
-/// use rand_os::rand_core::RngCore;
-/// use rand_os::OsRng;
-///
-/// let mut key = [0u8; 16];
-/// OsRng.fill_bytes(&mut key);
-/// let random_u64 = OsRng.next_u64();
