openssh: Build with Kerberos by default

This can be disabled with the `withKerberos` flag if desired. Make the relevant assertions lazy, so that if an overlay is used to set kerberos to null, a later override can explicitly set `withKerberos` to false. Don't build with GSSAPI by default; the patchset is large and a bit hairy, and it is reasonable to follow upstream who has not merged it in not enabling it by default.
