riscv, bpf: Fix RV32 broken build, and silence RV64 warning
Commit 252c765bd764 ("riscv, bpf: Add BPF exception tables") only addressed
RV64, and broke the RV32 build [1]. Fix by gating the exception tables code
with CONFIG_ARCH_RV64I.
Further, silence a "-Wmissing-prototypes" warning [2] in the RV64 BPF JIT.
