Subject: pkgs/top-level/all-packages.nix, pkgs/tools/networking/openssh:
 prefer makeOverridable over getPkgConfig to customize openssh

Changed 'openssh' expression to allow for argument overriding instead of
relying on getPkgConfig. While I was at it, I also simplified the build
expression a bit.
