PR11402 Support pipe2 syscall.

The pipe2() was added to Linux in version 2.6.27. It is a variant of the
normal pipe syscall, but takes an extra flags argument which can be the
ORed value of O_NONBLOCK and O_CLOEXEC.

* tapset/aux_syscalls.stp (_sys_pipe2_flag_str:string): New helper function.
* tapset/syscalls2.stp (syscall.pipe2, syscall.pipe2.return): New probes.
