gluon-wan-dnsmasq: read interfaces to update from flag-files (#2060)

Browse Source 
This commit changes the behavior for the wan-dnsmasq to read the
interfaces to update the DNS servers on from flag-files.

This way, external custom packages which add a custom VPN WAN interface
can update the DNS server gluon is using for WAN resolving.
