main: Add the option to run multiple zones at the same time

By default, zone-sync is parsing one zone, then updating it, and so on.
The main reason is that loading following zones could block the event
loop which means that an ongoing transfer can time out for no aparent
reason.

main: Unconditionally dump the zone

dns_zone_flush() does not always write the zone data. Since we call it
at point where we have definitely received some data (i.e. the zone has
changed), we can just force to dump it.

jenkins: Disable Fedora

The BIND headers seem to have been heavily patched and it is hard work
to make it compile. Since this is currently not really one of our target
platforms, I am just disabling building for Fedora.
