Fixed AddDependency in integration_type_support.go to handle default …

…case instead of discarding.

there was a problem handling --runtime xxx dependencies that got discarded:

        integration.Spec.AddDependency("runtime:" + o.Runtime)
    }```
and
```func (is *IntegrationSpec) AddDependency(dependency string) {
    switch {
    case strings.HasPrefix(dependency, "mvn:"):
        util.StringSliceUniqueAdd(&is.Dependencies, dependency)
    case strings.HasPrefix(dependency, "file:"):
        util.StringSliceUniqueAdd(&is.Dependencies, dependency)
    case strings.HasPrefix(dependency, "camel-"):
        util.StringSliceUniqueAdd(&is.Dependencies, "camel:"+strings.TrimPrefix(dependency, "camel-"))
    }
}```
were not cooping that well together resulting in any `--runtime` option to be discarded.
