Update nitrokey crate to 0.4.0

This change finally updates the version of the nitrokey crate that we
consume to 0.4.0. Along with that we update rand_core, one of its
dependencies, to 0.5.1. Further more we add cfg-if in version 0.1.10 and
getrandom in version 0.1.13, both of which are now new (non-development)
dependencies.

+# Common issues
+
+**Problem**: `rand_hc::Hc128Rng: rand_core::SeedableRng` (or other RNG)
+
+**Quick solution**: `cargo update`
+
+**Details**: This happens when multiple versions of the `rand_core` crate are in use. Check your `Cargo.lock` file for all versions of `rand_core`. Note that some versions (0.2.2 and 0.3.1) are compatibility shims and are not a problem by themselves.
