Merge branch 'libbpf_autoload_knob'

Andrii Nakryiko says:

====================
Add ability to turn off default auto-loading of each BPF program by libbpf on
BPF object load. This is the feature that allows BPF applications to have
optional functionality, which is only excercised on kernel that support
necessary features, while falling back to reduced/less performant
functionality, if kernel is outdated.
====================
