Kumar Kartikeya Dwivedi fd6094ac87 bpf: Reject tracing/freplace progs for struct_ops with arena args ...

Reject tracing and freplace attachments to a target program with arena
context arguments. The struct_ops indirect trampoline converts those
arguments before entering the target, so a generic tracing trampoline
would otherwise expose arena offsets using the target BTF pointer type.
