gss: krb5: remove signalg and sealalg
We designed the krb5 context import without completely understanding the
context. Now it's clear that there are a number of fields that we ignore,
or that we depend on having one single value.
In particular, we only support one value of signalg currently; so let's
check the signalg field in the downcall (in case we decide there's
something else we could support here eventually), but ignore it otherwise.
