Current working directory is a process level resource. We cannot call
chdir in parallel from multiple threads, which would cause cwd confusion
and result in UT failures.
The agent code itself is correct that chdir is only called from spawned
child init process. Well, there is one exception that it is also called
in do_create_container() but it is safe to assume that containers are
never created in parallel (at least for now).

`rustjail::erros` was removed in a previous commit, hence some external crates
like `error_chain` are no longger required, update Cargo.toml and Cargo.lock
to reflect these changes.

The scan_fmt crate has dependency on other four crates, and it's trivial
to use std library to implement the same logic. Get rid of scan_fmt to
reduce the dependency chain.

Use features to enable/disable slog and agent handler on demand.
This helps to reduce dependency chains if slog/agent handler is unused.

The netlink crate is a library to communicate with Linux kenrel by using
the netlink socket. It's generic enough to be reused by other clients.
So get rid of dependency on the rustjail crate by:
1) normalize all pub interfaces to return Result<T, nix::Error>,
2) add helpers to reduce duplicated code,
3) move parse_mac() into lib.rs,

Hardcode the Cargo.lock file to prevent dependencies
change which would cause some compatible issues.
