bpf: drop kthread_exit from noreturn_deny

commit 7fe44c4388146bdbb3c5932d81a26d9fa0fd3ec9 upstream.

kthread_exit became a macro to do_exit in commit 28aaa9c39945
("kthread: consolidate kthread exit paths to prevent use-after-free"),
so there is no kthread_exit function BTF ID to resolve. Remove it from
noreturn_deny to avoid resolve_btfids unresolved symbol warnings.
