hi,
sending the change to store and dump the license

v2 changes:
- dumping only the GPL compatible bool, without

# bpftool prog list
3: kprobe name func_begin tag 57cd311f2e27366b license GPL NON compatible
loaded_at Apr 25/11:20 uid 0
xlated 16B not jited memlock 4096B
# bpftool prog list
4: kprobe name func_begin tag 57cd311f2e27366b license GPL compatible
loaded_at Apr 25/11:20 uid 0
xlated 16B not jited memlock 4096B
# bpftool prog show --json
[{"id":3,"type":"kprobe","name":"func ... ,"gpl_compatible":false,"loade...
