Daniel Borkmann a4afd37b26 test_bpf: add tests related to BPF_MAXINSNS 
Couple of torture test cases related to the bug fixed in 0b59d8806a
("ARM: net: delegate filter to kernel interpreter when imm_offset()
return value can't fit into 12bits.").

I've added a helper to allocate and fill the insn space. Output on
x86_64 from my laptop:

test_bpf: #234 BPF_MAXINSNS: Single literal jited:0 8 PASS

test_bpf: #236 BPF_MAXINSNS: Too many instructions PASS
