[Documentation] EC2 Guide - bad command output after configuration file path change

The changes in JBEAP-12124 are good, but after reading through the docs there's one bad side-effect.

In "A.2. Example Configuration Files and Deployments" we say that there are two packages which add example configuration files and deployments. Yes there are, but now that the configuration paths refer to different configuration files, the command output for rpm -ql eap7-jboss-ec2-eap is not correct.

I suggest we only mention the package for example deployments (not configuration files) and say that the configuration files come from the EAP installation (still include system paths, but don't specify the RPM they come from).
