libgimpconfig: allow calling gimp_scanner_new_string (NULL, -1, ...) 

Allow calling gimp_scanner_new_string() with a NULL `text` and a
negative `text_len` (which is interpreted as 0), instead of
requiring `text_len == 0` in this case.  This allows passing a
negative `text_len` unconditionally to infer the length, even when
the string may be NULL.
