OpenSSH: allow users to configure --sysconfdir via $NIXPKGS_CONFIG

The OpenSSH binaries built by the expression by default expect system-wide
configuration files in "/etc/ssh", which is a bit of an impurity (and certainly
inconsistent with the way other package handle --sysconfdir in Nix). Those who
prefer a clean installation, can now configure that directory path.

Adding the line "openssh = { etcDir = null; };" to $NIXPKGS_CONFIG configures
OpenSSH to use the default location, i.e. $out/etc. Setting that attribute to a
string will configure OpenSSH to use that concrete path instead.
