tlv: Fix length returned by t{l16,16l}v_put
Every other function returns a pointer to the first byte after the tlv
that was just written.
tl16v seems to be a copy and paste error from tlv16 above and t16lv seems
to count the 16-bit tag twice.
The new tests verify that the return value of *_put(buf, tag, len, val)
points to buf + *_GROSS_LEN(len).
