Revert "Tell dnsmasq not to start wildcard sockets"

This reverts commit f1dfabed0a9b6ee9c37b64db3bbcb656281d4771.

The 3.4 kernel does not have SO_REUSEPORT functionality but the
headers #define it, so dnsmasq tries to use it and setsockopt
duly fails.

This is not a problem on 3.10 and later kernels, but reverting anyway.
