bpf: Trim special_kfunc_list in verifier
The commit 7619a0ee9340 ("bpf: Mark existing lock-safe kfuncs with KF_SPINLOCK_SAFE")
dropped some helpers in verifier, which also eliminated the use of the
following kfuncs from the special_kfunc_list:
* bpf_arena_reserve_pages
* bpf_stream_vprintk
* bpf_stream_print_stack
So, drop them from the special_kfunc_list.
