selftests/bpf: Do not fail build if CONFIG_NF_CONNTRACK=m/n

Some users have complained that selftests fail to build when
CONFIG_NF_CONNTRACK=m. It would be useful to allow building as long as
it is set to module or built-in, even though in case of building as
module, user would need to load it before running the selftest. Note
that this also allows building selftest when CONFIG_NF_CONNTRACK is
disabled.
