[pkg-opensc-maint] Bug#910786: opensc: No longer recognizes Yubikey NEO after upgrade to 0.16.0-3+deb9u1

It is still a problem with opensc/0.16.0-3+deb9u1 as currently available
from stretch. Backporting opensc/0.19.0-1 for stretch is trivial and has
resolved the problem for me and my colleagues.

I suggest fixing the problem in stretch via an update to 0.19 as
suggested by Adam D. Barratt in #913674.
