Update nitrokey crate to 0.3.3

This change updates the nitrokey crate to version 0.3.3. Along with that
change we update rand to 0.6.4 because rand 0.6.1 does not yet contain a
publicly accessible rand_os. Note that we no longer require all
crates in rand's workspace, but only rand_os and rand_core, which is a
significant reduction in the number of lines of code compiled.

+//! This crate implements the [xoshiro] family of pseudorandom number generators
+//! designed by David Blackman and Sebastiano Vigna. They feature high
+//! perfomance and a small state and superseed the previous xorshift-based
+//! generators. However, they are no cryptographically secure and their output
+//! can be predicted by observing a few samples.
+//!
+//! The following generators are implemented:
+//!
+//! # 64-bit generators
+//! - [`Xoshiro256StarStar`]: Recommended for all purposes. Excellent speed and
+//!   a state space (256 bits) large enough for any parallel application.
+//! - [`Xoshiro256Plus`]: Recommended for generating 64-bit floating-point
+//!   numbers. About 15% faster than `Xoshiro256StarStar`, but has a [low linear
+//!   complexity] in the lowest bits (which are discarded when generating
+//!   floats), making it fail linearity tests. This is unlikely to have any
+//!   impact in practise.
+//! - [`Xoroshiro128StarStar`]: An alternative to `Xoshiro256StarStar`, having
+//!   the same speed but using half the state. Only suited for low-scale parallel
+//!   applications.
+//! - [`Xoroshiro128Plus`]: An alternative to `Xoshiro256Plus`, having the same
+//!   speed but using half the state. Only suited for low-scale parallel
+//!   applications. Has a [low linear complexity] in the lowest bits (which are
+//!   discarded when generating floats), making it fail linearity tests. This is
+//!   unlikely to have any impact in practise.
+//! - [`Xoshiro512StarStar`]: An alternative to `Xoshiro256StarStar` with more
+//!   state and the same speed.
+//! - [`Xoshiro512Plus`]: An alternative to `Xoshiro512Plus` with more
+//!   state and the same speed. Has a [low linear complexity] in the lowest bits
+//!   (which are discarded when generating floats), making it fail linearity
+//!   tests. This is unlikely to have any impact in practise.
+//! - [`SplitMix64`]: Recommended for initializing generators of the xoshiro
+//!   familiy from a 64-bit seed. Used for implementing `seed_from_u64`.
+//!
+//! # 32-bit generators
+//! - [`Xoshiro128StarStar`]: Recommended for all purposes. Excellent speed.
+//! - [`Xoshiro128Plus`]: Recommended for generating 32-bit floating-point
+//!   numbers. Faster than `Xoshiro128StarStar`, but has a [low linear
+//!   complexity] in the lowest bits (which are discarded when generating
+//!   floats), making it fail linearity tests. This is unlikely to have any
+//!   impact in practise.
+//! - [`Xoroshiro64StarStar`]: An alternative to `Xoshiro128StarStar`, having
+//!   the same speed but using half the state.
+//! - [`Xoroshiro64Star`]: An alternative to `Xoshiro128Plus`, having the
+//!   same speed but using half the state. Has a [low linear complexity] in the
