firewalld: normalize new rich rules before comparing to old (bsc#1222684)

[m-czernek]

What does this PR do?

Firewallcmd rich rule output quotes each assigned part of the rich rule, for example: rule family="ipv4" source port port="161" ... The firewalld module must first normalize the user defined rich rules to match the firewallcmd output before comparison to ensure idempotency.
