Subject: [PATCH] bpf: print struct bpf_prog_info.gpl_compatible

This bit field was added by Linux commit v4.18-rc1~114^2~376^2~6.

* bpf_attr.h (struct bpf_prog_info_struct): Add gpl_compatible field.
* bpf.c (print_bpf_prog_info): Print gpl_compatible field.
* tests/bpf-obj_get_info_by_fd.c (main): Update expected output.
