Derive Default for libnitrokey structs

This patch adds the --with-derive-default option to the bindgen
invocation so that it derives Default implementations for all
libnitrokey structs.  This allows us to simplify code in nitrokey-rs,
for example the initialization of structs that are used in nitrokey-sys
functions with output parameters.
