From: Geliang Tang <tanggeliang@kylinos.cn>

New netns selftest helpers netns_new() and netns_free() has been added
in network_helpers.c, let's use them in mptcp selftests too instead of
using MPTCP's own helpers create_netns() and cleanup_netns().

v3:
 - No code has changed.
 - Change subject prefix as "bpf-next/net" since CI complains that this
patch cannot be merged.
 - Add Matt's Reviewed-by tag.

v2:
 - Use netns_new/netns_free instead of create_netns/cleanup_netns as
Martin suggested.

v1:
  selftests/bpf: Use make/remove netns helpers in mptcp
