kas: Don't require config for help

Modify the call to ka_Init in kas, so that a fully configured client
isn't required in order to generate help output. In particular, permit
kas -help, kas -version and kas apropos to run without initialising the
ka library.

This fixes a problem with running 'make check' on systems that don't
have an AFS client installed (or where the AFS client is installed in
a different location)
