Subject: [PATCH 1/5] selftests/bpf: Fix a fd leak in error paths in open_netns
As Martin mentioned in review comment, there is an existing bug that
orig_netns_fd will be leaked in the later "goto fail;" case after
open("/proc/self/ns/net") in open_netns() in network_helpers.c. This
patch adds "close(token->orig_netns_fd);" before "free(token);" to
fix it.
Fixes: a30338840fa5 ("selftests/bpf: Move open_netns() and close_netns() into network_helpers.c")

Subject: [PATCH 2/5] selftests/bpf: Use log_err in open_netns/close_netns
ASSERT helpers defined in test_progs.h shouldn't be used in public
functions like open_netns() and close_netns(). Since they depend on
test__fail() which defined in test_progs.c. Public functions may be
used not only in test_progs.c, but in other tests like test_sock_addr.c
in the next commit.
This patch uses log_err() to replace ASSERT helpers in open_netns()
and close_netns() in network_helpers.c to decouple dependencies, then
uses ASSERT_OK_PTR() to check the return values of all open_netns().

Subject: [PATCH 3/5] selftests/bpf: Use start_server_addr in test_sock_addr
Include network_helpers.h in test_sock_addr.c, use the newly added public
helper start_server_addr() instead of the local defined function
start_server(). This can avoid duplicate code.
In order to use functions defined in network_helpers.c in test_sock_addr.c,
Makefile needs to be updated and <Linux/err.h> needs to be included in
network_helpers.h to avoid compilation errors.
