bpf: fix missing prototype warnings
Compiling with W=1 generates warnings:
CC kernel/bpf/core.o
kernel/bpf/core.c:721:12: warning: no previous prototype for ?bpf_jit_alloc_exec_limit? [-Wmissing-prototypes]
721 | u64 __weak bpf_jit_alloc_exec_limit(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~
kernel/bpf/core.c:757:14: warning: no previous prototype for ?bpf_jit_alloc_exec? [-Wmissing-prototypes]
757 | void *__weak bpf_jit_alloc_exec(unsigned long size)
| ^~~~~~~~~~~~~~~~~~
kernel/bpf/core.c:762:13: warning: no previous prototype for ?bpf_jit_free_exec? [-Wmissing-prototypes]
762 | void __weak bpf_jit_free_exec(void *addr)
| ^~~~~~~~~~~~~~~~~
All three are weak functions that archs can override, provide
proper prototypes for when a new arch provides their own.
