Bug#1021875: dh-python: dh_python3 does not support --remaining-packages

[Andreas Beckmann]

Source: dh-python
Severity: normal

Hi,

I just tried giving some custom flags for some packages to dh_python3
and finish that override target with dh_python3 --remaining-packages,
but that causes a failure due to the unrecognized fag.
