Update nitrokey crate to 0.2.3

This change updates the nitrokey crate to version 0.2.3. This version
bumps the rand crate used to 0.6.1, which in turn requires an additional
set of dependencies.

+# We support too many combinations of Rust releases, crate features, operating
+# systems, and architectures to even remotely test all combinations.
+# Yet it turns out we can test most of these independent of each other, because
+# they serve different goals or test different pieces of code.
+#
+# RUST RELEASES
+# Goal: make sure we don't use language features unavailable on a certain
+#       version, and build without warnings.
+# We have different builders use 4 Rust releases, a pinned stable release,
+# the latest stable, beta and nightly.
+#
+# ARCHITECTURES
+# Goal: test against issues caused by differences in endianness, pointer sizes,
+#       etc.
+# We run tests on 4 different architectures.
+# - x64_84, default on Travis (Linux) and AppVeyor (Windows)
+# - i686, second AppVeyor (Windows) configuration
+# - MIPS, big-endian Linux emulated with QEMU (thanks to Trust)
+# - ARMv7, Android emulated with QEMU (thanks to Trust)
+#
+# OPERATING SYSTEMS
+# Goal: test on many operating systems, to verify the OsRng code, which is
+#       mostly architecture-independent.
+# We run tests on Linux, OS X, Windows, Android (emulated), and Node.js (using
+# cargo-web).
+# One builder cross-compiles for many of the remaining OSes, which ensures we
+# keep building, but doesn't run tests.
+# OSes supported by Rand but which we can't cross-compile because there
+# is no pre-built standard library available: Dragonfly BSD, Haiku, OpenBSD.
+#
+# CRATE FEATURES, TESTS, AND SUB-CRATES
+# Goal: Run unit tests, doctests, examples, and test benchmarks for all crates,
+#       in configurations that cover all interesting combinations of features.
+# (`--lib` only runs unit tests just like `--tests`, but the latter is not
+# available in Rust 1.22.0)
+# Tests run on rand:
+# - test no_std support, but only the unit tests:
+#   `cargo test --lib --no-default-features`
+# - run unit tests and doctests with all features which are available on stable:
+#   `cargo test --features=serde1,log`
+# - test examples:
+#   `cargo test --examples`
+# Additional tests on nightly:
+# - run unit tests and doctests with all features which are available on nightly:
+#   `cargo test --all-features`
+# - test no_std support, including the nightly alloc feature:
+#   cargo test --lib --no-default-features --features=alloc
+# - run benchmarks as tests:
+#   `cargo test --benches --features=nightly`
+# Tests on subcrates:
+# - select crates via --manifest-path (more reliable than --package)
+# - test appropriate feature matrix
+#
+# TODO: SIMD support on stable releases
+# NOTE: SIMD support is unreliable on nightly; we track the latest release
