run_fork_with_timeout: allow returning complex structures

Encode the result or the error in JSON. This way complex objects or
exceptions may be passed to the parent in a generic way.

This allows to remove the second pipe 'pipe_err'.

Allow also to return undef without any warnings to our caller.
This avoids a "use of uninitialized variable ..." warning
