Add module for taking ownership of inherited file descriptors (#56)

* Move inherited_fds module from rustutils library.

* Clean up and fix for new version of nix.

* Run tests with cargo-nextest.

The inherited FD tests need to be run in separate processes, which this
achieves.

* Add child process example to readme and rustdoc.

* Add changelog.
