This patch removes all dependencies that are no longer required since
the hidapi communication is replaced by libnitrokey.

-//! A build dependency for Cargo libraries to find system artifacts through the
-//! `pkg-config` utility.
-//!
-//! This library will shell out to `pkg-config` as part of build scripts and
-//! probe the system to determine how to link to a specified library. The
-//! `Config` structure serves as a method of configuring how `pkg-config` is
-//! invoked in a builder style.
-//!
-//! A number of environment variables are available to globally configure how
-//! this crate will invoke `pkg-config`:
-//!
-//! * `PKG_CONFIG_ALLOW_CROSS` - if this variable is not set, then `pkg-config`
-//!   will automatically be disabled for all cross compiles.
-//! * `FOO_NO_PKG_CONFIG` - if set, this will disable running `pkg-config` when
-//!   probing for the library named `foo`.
-//!
-//! There are also a number of environment variables which can configure how a
-//! library is linked to (dynamically vs statically). These variables control
-//! whether the `--static` flag is passed. Note that this behavior can be
-//! overridden by configuring explicitly on `Config`. The variables are checked
-//! in the following order:
-//!
-//! * `FOO_STATIC` - pass `--static` for the library `foo`
-//! * `FOO_DYNAMIC` - do not pass `--static` for the library `foo`
-//! * `PKG_CONFIG_ALL_STATIC` - pass `--static` for all libraries
-//! * `PKG_CONFIG_ALL_DYNAMIC` - do not pass `--static` for all libraries
-//!
-//! After running `pkg-config` all appropriate Cargo metadata will be printed on
-//! stdout if the search was successful.
-//!
-//! # Example
-//!
-//! Find the system library named `foo`, with minimum version 1.2.3:
-//!
-//! ```no_run
-//! extern crate pkg_config;
-//!
-//! fn main() {
-//!     pkg_config::Config::new().atleast_version("1.2.3").probe("foo").unwrap();
-//! }
-//! ```
-//!
-//! Find the system library named `foo`, with no version requirement (not
-//! recommended):
-//!
-//! ```no_run
-//! extern crate pkg_config;
-//!
-//! fn main() {
-//!     pkg_config::probe_library("foo").unwrap();
-//! }
-//! ```
-//!
-//! Configure how library `foo` is linked to.
-//!
-//! ```no_run
-//! extern crate pkg_config;
-//!
-//! fn main() {
-//!     pkg_config::Config::new().atleast_version("1.2.3").statik(true).probe("foo").unwrap();
-//! }
-//! ```
