[PATCH bpf-next 4/4] selftests/bpf: Drop __start_server in network_helpers

[Geliang Tang <geliang@xxxxxxxxxx>]

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

The helper start_server_addr() is a wrapper of __start_server(), the
only difference between them is __start_server() accepts a sockaddr type
address parameter, but start_server_addr() accepts a sockaddr_storage one.

This patch drops __start_server(), and updates the callers to invoke
start_server_addr() instead.
