Add first set of integration tests

This change introduces the first set of integration-style test for the
application. Those tests may or may not connect to an actual Nitrokey
device (depending on what they test). We use the nitrokey-test crate's
test attribute macro to automatically dispatch tests to connected
devices or skip them if a required device is not present. It also
provides the means for automatically serializing tests.
