til_settings: add til_settings_get_label() getter

Preparatory commit for rkt_scener scenes editing, which will be
replacing the current scene's settings instance with a newly
constructed one.  This enables simply duplicating the existing
scene setting's positional label, which will be identical in the
replacement.
