gitian: upgrade miniupnpc input to 1.9

Bumps deps-linux, deps-win dependency versions as well.

qt-win does not need to be bumped, as although it depends on deps-win,
Qt doesn't use miniupnp. I verified this by rebuilding the dependency
and checking the the output is the same. Not having to rebuild Qt is a
good thing as it is huge.
