As reported by Baptiste in GH #2797, if a logformat alias leveraging lf_text() ends up printing nothing (empty string), the whole logformat evaluation stops, leading garbage log message. This bug was introduced during 3.0 cycle in fcb7e4b ("MINOR: log: add lf_rawtext{_len}() functions"). At that time I genuinely thought that if strlcpy2() returned 0, it was due to a lack of space, actually forgetting that the function may simply be called with an empty string. Because of that, lf_text() would return NULL if called with an empty string, and since all lf_*() helpers are expected to return NULL on error, this explains why the logformat evaluation immediately stops in this case. To fix the issue, let's simply consider that strlcpy2() returning 0 is not an error, like it was already the case before. It should be backported in 3.1 and 3.0 with fcb7e4b.
