Since we are now running with openjdk instead of oracle java, we should

1. Install the traffic router via yum/rpm instead of unpacking it with rpm2cpio. I used the rpm2cpio method at the time due to issues in the RPMs that no longer exist.
2. We don't need to build the tomcat-native manually at this point and can just install tomcat-native via yum/rpm.

Why not :

ADD $TRAFFIC_ROUTER_RPM /
ADD $TOMCAT_RPM /

RUN yum install -y /$( basename $TOMCAT_RPM)
RUN yum install -y /$( basename $TRAFFIC_ROUTER_RPM)

This builds and runs in CIAB, and now that it's using yum instead of rpm2cpio I think this should work perfectly - pending #2960 to get Traffic Router to build for OpenJDK
