Use conditional compilation (#[cfg]) to change pivot_root behaviour
at compilation time. For example, such function will just return
`Ok(())` when the unit tests are being compiled, otherwise real
pivot_root operation is performed.

Don't use unwrap in `init_rootfs` instead return an Error, this way
we can write unit tests that don't panic.

The version.rs file is now generated to contain up-to-date information
from the makefile, including git commit and the full binary path.
The makefile has also been modified to make it easier to add changes
in generated files based on makefile variables.

`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.

Don't use `rustjail::errors` for error handling, since it's not
thread safe and there are better alternatives like `anyhow`.
`anyhow` attaches context to help the person troubleshooting
the error understand where things went wrong, for example:
Current error messages:
```
No such file or directory (os error 2)
```
With `anyhow`:
```
Error: Failed to read config.json
Caused by:
No such file or directory (os error 2)
```

The logic for the debug console meant that if the debug console was
_disabled_, the agent was guaranteed to crash on function exit due to
the unsafe code block. Fixed by simplifying the code to use the standard
`Option` idiom for optional values.
