sbuf(9): Add sbuf_nl_terminate() API
The API is used to gracefully terminate text line(s) with a single \n. If
the formatted buffer was empty or already ended in \n, it is unmodified.
Otherwise, a newline character is appended to it. The API, like other
sbuf-modifying routines, is only valid while the sbuf is not FINISHED.
