cmake: disable kafka when not found

This should fix the issue of incompatible librdkafka in ubuntu-xenial
This does not apply to octopus (or newer) since ubuntu-xenial is
not supported for them.
Note that this change automatically changes the users build directives,
which we would not like to carry forward to newer versions.
