extmod/os_dupterm: Let mp_os_dupterm_tx_strn() return num bytes written.
In case of multiple outputs, the minimum successful write length is
returned. In line with this, in case any output has a write error, zero is
returned.
In case of no outputs, -1 is returned.
The return value can be used to assess whether writes were attempted, and
if so, whether they succeeded.
