Martin KaFai Lau 7d3851a318 selftests/bpf: Sanitize the SEC and inline usages in the bpf-tcp-cc tests
It is needed to remove the BPF_STRUCT_OPS usages from the tcp-cc tests
because it is defined in bpf_tcp_helpers.h which is going to be retired.
While at it, this patch consolidates all tcp-cc struct_ops programs to
use the SEC("struct_ops") + BPF_PROG().

It also removes the unnecessary __always_inline usages from the
tcp-cc tests.
