powerpc/bpf: Remove classical BPF support for PPC32
At the time being, PPC32 has Classical BPF support.
The test_bpf module exhibits some failure:
test_bpf: #298 LD_IND byte frag jited:1 ret 202 != 66 FAIL (1 times)
test_bpf: #299 LD_IND halfword frag jited:1 ret 51958 != 17220 FAIL (1 times)
test_bpf: #301 LD_IND halfword mixed head/frag jited:1 ret 51958 != 1305 FAIL (1 times)
test_bpf: #303 LD_ABS byte frag jited:1 ret 202 != 66 FAIL (1 times)
test_bpf: #304 LD_ABS halfword frag jited:1 ret 51958 != 17220 FAIL (1 times)
test_bpf: #306 LD_ABS halfword mixed head/frag jited:1 ret 51958 != 1305 FAIL (1 times)
test_bpf: Summary: 371 PASSED, 7 FAILED, [119/366 JIT'ed]
Fixing this is not worth the effort. Instead, remove support for
classical BPF and prepare for adding Extended BPF support instead.
