[bpf-next,v7,2/9] selftests/bpf: Use start_server_str in sockmap_ktls

Commit Message

From: Geliang Tang <[e-mail]>

Include network_helpers.h in prog_tests/sockmap_ktls.c, use public network
helper start_server_str() instead of local defined function tcp_server().
This can avoid duplicate code.

Technically, this is not a one-for-one replacement, as start_server_str()
also does bind(). But the difference does not seem to matter.
