bpf, arm: Remove dummy bpf_jit_compile stub

The BPF core defines a __weak bpf_jit_compile() dummy function already
which should only be overridden by JITs if they actually implement a
legacy cBPF JIT. Given arm implements an eBPF JIT, this stub is not

Now that MIPS cBPF JIT is finally gone, the only JIT left that is still
implementing bpf_jit_compile() is the sparc32 one.
