Turn libbpf's kernel feature probing into lazily-performed checks. This allows to skip performing unnecessary feature checks, if a given BPF application doesn't rely on a particular kernel feature. As we grow number of feature probes, libbpf might perform less unnecessary syscalls and scale better with number of feature probes long-term. By decoupling feature checks from bpf_object, it's also possible to perform feature probing from libbpf static helpers and low-level APIs, if necessary.
