Remove runtime provided libraries from HTTP connector

Since Mule 4.2.2 we are logging a warning when a connector is using a package that's being loaded at the runtime level and ignored from the plugin classloader:

WARN 2019-09-05 16:45:32,134 [WrapperListener_start_runner] [event: ] org.mule.runtime.deployment.model.internal.DefaultRegionPluginClassLoadersFactory: Plugin 'HTTP' contains a local package 'com.sun.activation.viewers', but it will be ignored since it is already available from the container.

We need to remove those libraries from HTTP connector
