selftests/bpf: Fix cgroup sockopt verifier test 

Since the BPF_PROG_TYPE_CGROUP_SOCKOPT verifier test does not set an
attach type, bpf_prog_load_check_attach() disallows loading the program
and the test is always skipped:

 #434/p perfevent for cgroup sockopt SKIP (unsupported program type 25)

Fix the issue by setting a valid attach type.

Fixes: 0456ea170c ("bpf: Enable more helpers for BPF_PROG_TYPE_CGROUP_{DEVICE,SYSCTL,SOCKOPT}")
