realtek: Remove dnsmasq and odhcpd-ipv6only from default
Do not include the dnsmasq and odhcpd-ipv6only package by default any
more. These services are not needed on a switch. If someone needs this
it is still possible to use opkg or image builder to add them.
This decreases the compressed image size by about 165KBytes.
