Avahi: Don't start the avahi-daemon if dot local domain is there

More info is at the following link

This commit creates the avahi user and avahi group,as there may be cases
where one of them don't exist due to code update.

for example a BMC image that has additional user accounts
(and therefore a bigger /etc/group file) is installed on the BMC,
the /etc/group or /etc/passwd file would not be updated because is part of the
persistent files, so the old /etc/group or /etc/passwd file would remain.

Tested: 1) System which doesn't have avahi group,With this fix creates the
            group and start the avahi daemon.
        2) Verified on the system where there is a zone
           .local is being used by the DNS server,avahi-daemon was not started.

Resolves openbmc/openbmc#2788
