core: fix the check if CONFIG_CGROUP_BPF is on

Since the commit torvalds/linux@fdb5c4531c1e0e50e609df83f736b6f3a02896e2
the syscall BPF_PROG_ATTACH return EBADF when CONFIG_CGROUP_BPF is
turned off and as result the bpf_firewall_supported() returns the
incorrect value.

This commmit replaces the syscall BPF_PROG_ATTACH with BPF_PROG_DETACH
which is still work as expected.

Resolves openbmc/linux#159
See also systemd/systemd#7054
