[bpf-next,4/8] selftests/bpf: Replace tx_prog_fd with tx_prog in test_sockmap

From: Geliang Tang <tanggeliang@kylinos.cn>

bpf_program__attach_sockmap() needs to take a parameter of type bpf_program
instead of an fd, so tx_prog_fd becomes useless. This patch uses a pointer
tx_prog to point to an item in progs[] array.
