Subject: [PATCH bpf-next 1/3] bpf/bpftool: add syscall prog type

In addition to displaying the program type in bpftool prog show
this enables us to be able to query bpf_prog_type_syscall
availability through feature probe as well as see
which helpers are available in those programs (such as
bpf_sys_bpf and bpf_sys_close)
