ptrace: ptrace_attach: use send_sig_info() instead force_sig_specific()
Nobody can block/ignore SIGSTOP, no need to use force_sig_specific() in ptrace_attach. Use the "regular" send_sig_info(). With this patch stracing of /sbin/init doesn't clear its SIGNAL_UNKILLABLE, but not that this makes ptracing of init safe.
