insane: Recognise BPF as a valid EM_MACHINE type

Browse Source 
BPF Linux ELF objects are generated with kernel-selftests with
>= 4.18 kernel and when clang is enabled which packages BPF objects
into packages, therefore recongnise this as a valid ELF target

Add a selftest for BPF

Do not flag BPF objects in target, since they pretty much will be ok for
most of kernels architectures we care do support BPF
