Andrei Vagin 17c18241cd platform/syscall: use syscall + int3 to execute a system call in a stub process 
Right now, we need to call ptrace(PTRACE_SYSCALL) and wait() twice to execute
one system call in a stub process. With these changes, we will need to call
ptrace + wait only once.

In addition, this allows to workaround the kernel bug when a stub process
doesn't stop on syscall-exit-stop and starts executing the next system call.
