redhat: kauth client and server sub-packages
Move the kaserver and kauth client programs to conditionally built
packages called openafs-kauth-server and openafs-kauth-client.
Packagers can build these by specifying '--with kauth'. They are not
built by default to discourage use.
This commit subsumes the openafs-kpasswd package into the
openafs-kauth-client package.
