These hooks are not useful for BPF LSM currently.
Furthermore a recent renaming introduced build warnings:
BTFIDS vmlinux
WARN: resolve_btfids: unresolved symbol bpf_lsm_task_getsecid_obj
WARN: resolve_btfids: unresolved symbol bpf_lsm_current_getsecid_subj
Link: https://lore.kernel.org/lkml/20241123-bpf_lsm_task_getsecid_obj-v1-1-0d0f94649e05@weissschuh.net/
Fixes: 37f670aacd48 ("lsm: use lsm_prop in security_current_getsecid")
Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>

Changes in v2:
- Delete instead of rename IDs
- Link to v1: https://lore.kernel.org/r/20241123-bpf_lsm_task_getsecid_obj-v1-1-0d0f94649e05@weissschuh.net
