bpf: fix missing prototype warnings

[ Upstream commit 116bfa96 ]

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.
