dns: update caching plugins on configuration change signal

Browse source 
A HUP or USR1 signal forces the rewrite of DNS configuration, however
caching plugins are ignored when using dns=dnsmasq and so the real
servers are written to resolv.conf:

 $ cat /etc/resolv.conf
 nameserver 127.0.0.1

 # killall -USR1 NetworkManager

 $ cat /etc/resolv.conf
 nameserver 192.168.1.1

Set @no_caching to FALSE when calling update_dns() after a signal to
take caching plugins into account.
