dnsmasq: allow dnsmasq variants to be included in image

The dnsmasq variants should provide dnsmasq, otherwise it is impossible
to include them in the image.

This change allows one to have CONFIG_PACKAGE_dnsmasq=m and
CONFIG_PACKAGE_dnsmasq-full=y, e.g. because you want DNSSEC support, or
IPSETs suport on your 3000-devices fleet ;-)
