lib.ExecContext: Code beautification

- Move _sudo() above sudo()

    To have a pattern in lib.ExecContext and avoid future churn: If a
    public wrapper calls a protected method, define the protected
    method above the respective wrapper.

  - sudo(): Make cmd_input default equal to run(): InputMode.OptInteractive

  - CallContext: Expose parameters throw, wd, cmd as properties for
    later use
