eap7-wildfly RPM package requires jdk8 on RHEL7

Current build of eap7-wildfly package for EAP7.3.0.Beta on RHEL7 requires JDK8 directly. This is wrong as since 7.2.0 we support both JDK8 and JDK11. As such, new eap7-wildfly-java-jdk11 and eap7-wildfly-java-jdk8 metapackages have been introduced since EAP7.2.1 as a fix for JBEAP-16017. These provide eap7-wildfly-java item which has been part of eap7-wildfly package since EAP7.2.1. This does not apply to current EAP7.3.0.Beta release:

# rpm -q --requires eap7-wildfly
/bin/sh
/bin/sh
/bin/sh
/bin/sh
/bin/sh
config(eap7-wildfly) = 0:7.3.0-4.Beta_redhat_00001.1.el7eap
eap7-runtime
eap7-runtime
eap7-wildfly-modules
java >= 1:1.8
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
shadow-utils
systemd-units
systemd-units
systemd-units
rpmlib(PayloadIsXz) <= 5.2-1

I believe we should ditch the 'java >= 1:1.8' record from there and add 'eap7-wildfly-java' instead.

This discrepancy may not be a big issue if customer installs EAP via yum group command as group definition contains appropriate requirements. Although, I believe we should keep consistent to what we introduced in previous releases.
