Subject: [PATCH] bpf, lsm: Fix getlsmprop hooks BTF IDs

The hooks got renamed, adapt the BTF IDs.
Fixes the following build warning:

  BTFIDS  vmlinux
WARN: resolve_btfids: unresolved symbol bpf_lsm_task_getsecid_obj
WARN: resolve_btfids: unresolved symbol bpf_lsm_current_getsecid_subj

Fixes: 37f670aacd48 ("lsm: use lsm_prop in security_current_getsecid")
