dnsmasq: rework jail mounts (#7578)

Browse Source 
* split into multiple lines to improve readability
 * use EXTRA_MOUNT for addnhosts instead of blindly adding /tmp/hosts
 * remove no longer needed mount for /sbin/hotplug-call
 * add dhcp-script.sh dependencies (jshn, ubus)

Fixes: 3a94c2ca5c ("dnsmasq: add /tmp/hosts/ to jail_mount")
Fixes: aed95c4cb8 ("dnsmasq: switch to ubus-based hotplug call")
