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.

+
+### Fixed
+- Bump `cfg-if` minimum version from 0.1.0 to 0.1.2. [#112]
+- Typos and bad doc links. [#117]
