Do not trace children cloned with CLONE_UNTRACED flag
Do not trace children cloned with CLONE_UNTRACED flag

If clone is called with flag CLONE_UNTRACED, to be consistent with
option PTRACE_O_TRACECLONE, we should not set CLONE_PTRACE flag on
its arguments.

* process.c [LINUX] (internal_fork): Check the syscall and arguments.
