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.
