The rpm file "eap7-jboss-seam-int-0:7.0.0-1.GA_redhat_1.1.ep7.el6.noarch.rpm" contains jar named "jboss-seam-int-jbossas-7.0.0.GA-redhat-1.jar".

The corresponding file in the the zip in the location:
modules/system/layers/base/org/jboss/integration/ext-content/main/bundled/
has name jboss-seam-int.jar.

Fix is to add "jbossas" string to the jar file name in the dist.
