ptrace: x86: change syscall_trace_leave() to rely on tracehook when stepping
Suggested by Roland.
Unlike powepc, x86 always calls tracehook_report_syscall_exit(step) with
step = 0, and sends the trap by hand.
This results in unnecessary SIGTRAP when PTRACE_SINGLESTEP follows the
syscall-exit stop.
Change syscall_trace_leave() to pass the correct "step" argument to
tracehook and remove the send_sigtrap() logic.
