Bug#1003046: openssh-client-ssh1: use /etc/ssh/ssh1_config as default config file

Package: openssh-client-ssh1
Version: 1:7.5p1-17
Followup-For: Bug #1003046

Dear Maintainer,

This has become more important with the removal of old protocols
from upstream openssh.  This package attempts to read a configuration
file meant for openssh-client, and errors out.  I'm maintaining a parallel
version that looks in /etc/ssh1 and ~/.ssh1 to stop the two from
conflicting since installing ssh1 is now mandatory to access older hardware.

As the two continue to diverge the incompatibility will only grow.
