selftests/bpf: Avoid pinning bpf prog in the netns_load_bpf() callers

Browse source

This patch removes the need to pin prog in the remaining tests in
tc_redirect.c by directly using the bpf_tc_hook_create() and
bpf_tc_attach().  The clsact qdisc will go away together with
the test netns, so no need to do bpf_tc_hook_destroy().
