UPSTREAM: <carry>: don't use --prefers-protobuf with client-gen

kcp doesn't implement protobuf codec yet, and so we need to disable it in the
client code.

This commit comments out --prefers-protobuf command line flag when invoking
client-gen in update-codegen.sh scripts in various places.

TODO: revert once kcp gains protobuf support.
