libbpf: Add probe for large INSN limit
Introduce a new probe which checks whether kernel has large maximum
program size which was increased in the following commit:
c04c0d2b968a ("bpf: increase complexity limit and maximum program size")
Based on the similar check in Cilium[0], authored by Daniel Borkmann.
