Replace connman's DNS with dnsmasq

Stop connman from managing DNS

You need to add the --nodnsproxy proxy flag to connmand. This can be done by runing devel-su systemctl edit connman and pasting this into there:

[Service]
ExecStart=
ExecStart=/usr/sbin/connmand -n -W nl80211 --nobacktrace --noplugin=wifi --nodnsproxy $SYSCONF_ARGS $CONNMAN_ARGS

Afterwards run devel-su systemctl restart connman.
