[Bug tapsets/11402] New: pipe2 syscall not supported

["mjw at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

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. The original pipe syscall is now defined as like the
pipe2 syscall, but with the flags variable set to zero.

Should we support this (in syscall2.stp) as an extra syscall, or should we
retrofit the syscall.pipe probe alias to also match sys_pipe2?
