packaging: correct permissions in spec file and fix class path specified variable (#3030)

Install CentOS 7 e.g. Build 1804 and Java build 1.8.0_181

if you inspect systemd in debug mode you will see some errors
1.
permission of the cloudstack-managment.service are not corretly set
2.
invalid classpath specified. it seems the string which is used will be divided... we now we use ${..} like the lines above ... confused
