Due to changed vdso layout in modern kernels (at least 6.2), linux injector when parsing vdso in
find_syscallcan first find the address of the trap we are already standing on. This leads to a violation of the injection logic.So in this case we can simply skip first occurence of
syscallcall in vdso and try to find next.
