[Bug tapsets/11406] New: Add dup2, epoll_create1, eventfd2, inotify_init1 and signalfd4 to syscall tapset

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

Together with pipe2 (see bug #11402) other system calls that create a file
descriptor (dup2, epoll_create1, eventfd2, inotify_init1 and signalfd4) were
introduced that let the user set flags on the fd from the start (so one doesn't
need to call fcntl() afterwards).

At the same time the socket, socketpair and timerfd_create got CLOEXEC and
NONBLOCK flags (partly already handled by commit 3651ea for open, who got this
support in 2.6.23 already).

(Which describes the view from the user space side, not the actual kernel side
system call changes)
