ptrace: introduce user_single_step_siginfo() helper
Suggested by Roland.
Currently there is no way to synthesize a single-stepping trap in the
arch-independent manner. This patch adds the default helper which fills
siginfo_t, arch/ can can override it.
Architetures which implement user_enable_single_step() should add
user_single_step_siginfo() also.
