tar: Always use correct length in safe_fprintf

If the format buffer shall not be further increased in size, the
length value mistakenly takes the terminating nul byte into account.

This is in contrast to a successful vsnprintf call.

Also use the correct string length if fallback to stack buffer is
required.
