selftests: bpf: Fix detach from sockmap tests
Fix sockmap tests which rely on old bpf_prog_dispatch behaviour.
In the first case, the tests check that detaching without giving
a program succeeds. Since these are not the desired semantics,
invert the condition. In the second case, the clean up code doesn't
supply the necessary program fds.
Fixes: bb0de3131f4c ("bpf: sockmap: Require attach_bpf_fd when detaching a program")
