David Laight 4045e7b19b tools/nolibc/printf: Move snprintf length check to callback ...

Move output truncation to the snprintf() callback.
This simplifies the main code and fixes truncation of padded fields.

Add a zero length callback to 'finalise' the buffer rather than
doing it in snprintf() itself.
