Use a header-cast in nd_syscall.sigaltstack
The nd_syscalls tapset is meant to run with no debuginfo, so using a @cast into a module type defeats the purpose. We should use a @cast with a header name instead, so debuginfo is generated. * tapset/i386/nd_syscalls.stp (nd_syscall.sigaltstack): Get the pt_regs type definition from "kernel<asm/ptrace.h>".
