bpf/bpftool: add syscall prog type
88ab9e9 
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)

bpf/bpftool: handle libbpf_probe_prog_type errors
5eba196 
Previously [1], we were using bpf_probe_prog_type which returned a
bool, but the new libbpf_probe_bpf_prog_type can return a negative
error code on failure. This change decides for bpftool to declare
a program type is not available on probe failure.

bpf, arm64: bpf trampoline for arm64
627ebd4 
Add bpf trampoline support for arm64. Most of the logic is the same as
x86.

fentry before bpf trampoline hooked:
 mov x9, x30
 nop

fentry after bpf trampoline hooked:
 mov x9, x30
 bl  <bpf_trampoline>

Tested on qemu, result:
 #18  bpf_tcp_ca:OK
 #51  dummy_st_ops:OK
 #55  fentry_fexit:OK
 #56  fentry_test:OK
