[7.2.z] Default settings of jboss-eap-rhel.sh doesn't work on RHEL8

Default settings of jboss-eap-rhel.sh doesn't work on RHEL8. EAP service is not started.

Script is unable to access to "/log" folder on RHEL8, see the details from "journalctl --since=today --unit=jboss-eap-rhel":

Oct 08 12:54:31 rhel8-medium-2609 jboss-eap-rhel.sh[7044]: Starting jboss-eap: /etc/rc.d/init.d/jboss-eap-rhel.sh: line 104: /var/log/jboss-eap/console.log: Permission denied
Oct 08 12:54:31 rhel8-medium-2609 jboss-eap-rhel.sh[7044]: /etc/rc.d/init.d/jboss-eap-rhel.sh: line 113: /var/log/jboss-eap/console.log: Permission denied

Workarounds:

1. manually set permissions to proper EAP log folders (by default jboss-eap):

   mkdir -p /var/log/jboss-eap
   chmod 777 /var/log/jboss-eap
   touch /var/log/jboss-eap/console.log
   chmod 777 /var/log/jboss-eap/console.log
   

2. Use different path to console logs:

   echo "JBOSS_CONSOLE_LOG=/tmp/user/console.log" >> /home/hudson/hudson_workspace/workspace/mkopecky/jboss-eap-7.3/bin/init.d/jboss-eap.conf
   echo "JBOSS_CONSOLE_LOG=/tmp/user/console.log" >> /etc/default/jboss-eap.conf
