examples/dnsclient_test: make dns server port configurable in .config

This patch enables dnsclient_test app's server port to be configurable
in .config. You can set dns server's port number using the following
config variable.
 - CONFIG_EXAMPLES_DNSCLIENT_TEST_SERVER_PORT

CONFIG_EXAMPLES_DNSCLIENT_TEST_SERVER_PORT can be configurable only
when CONFIG_NETDB_DNSSERVER_IPv4 is enabled.
