Andrii Nakryiko 2eda2145eb libbpf: Preserve kernel error code and remove kprobe prog type guessing
Instead of rewriting error code returned by the kernel of prog load with
libbpf-sepcific variants pass through the original error.

There is now also no need to have a backup generic -LIBBPF_ERRNO__LOAD
fallback error as bpf_prog_load() guarantees that errno will be properly
set no matter what.

Also drop a completely outdated and pretty useless BPF_PROG_TYPE_KPROBE
guess logic. It's not necessary and neither it's helpful in modern BPF
applications.
