[Test] Skip MdnsIPv6LinkLocalWithDefaultRoute on Kernel 4.4 

The test failed on kernel 4.4 since the kernel does not provide an IPv6
link-local address when an interface is added to a network. The IPv6
link-local address is a prerequisite for this test. Considering 4.4 is
outdated and EOL'ed, skip the test directly.

netd    : networkAddInterface(10000, "testtun10000") <2.79ms>

$ adb shell ifconfig
