Exclude servlet-api and Jetty JARs from Cobertura classpath. It works without them.

Exclude AprSocket class from instrumentation.

Cobertura fails to instrument it, because it causes loading jni.socket.AprSocketContext and jni.Library
which fails when tcnative library is absent in java.library.path.

No need to backport, as this class is absent in Tomcat 7.
