Brings in a variety of changes, mostly to the containerd shim.
There is also a change to the Windows layer unpack code which fixes#4301.

- unix: add Darwin support for clonefile syscalls
- Adds openat2 for linux
openat2 is a new syscall added to Linux 5.6. It provides a superset of
openat(2) functionality, extending it with flags telling the kernel how
to resolve the paths.
For more info, see https://lwn.net/Articles/803237/
NOTE that this is a second attempt to add the call; the previous one
(https://golang.org/cl/227280) was reverted
(https://golang.org/cl/227846) due to the test case failure on ARM
(https://golang.org/issue/38357).
This CL has the test case reworked to be less assumptive to the testing
environment. In particular, it first tries if the most simplistic
openat2() call succeeds, and skips the test otherwise. It is done that
way because CI can be under under different kernels and in various
envrionments -- in particular, Docker+seccomp can result in EPERM from a
system call (which is not expected otherwise).
For previous discussions about the test case, see
https://golang.org/cl/227865.

The maintainers discussed extending the end of life date for 1.2
to allow time for EOL announcement and migration to 1.3.

The tricks performed by ensureRemoveAll only make sense for Linux and
other Unices, so separate it out, and make ensureRemoveAll for Windows
just an alias of os.RemoveAll.

The shim delete action needs bundle information to cleanup resources
created by shim. If the cleanup dead shim is called after delete bundle,
the part of resources maybe leaky.
The ttrpc client UserOnCloseWait() can make sure that resources are
cleanup before delete bundle, which synchronizes task deletion and
cleanup deadshim. It might slow down the task deletion, but it can make
sure that resources can be cleanup and avoid EBUSY umount case. For
example, the sandbox container like Kata/Firecracker might have mount
points over the rootfs. If containerd handles task deletion and cleanup
deadshim parallelly, the task deletion will meet EBUSY during umount and
fail to cleanup bundle, which makes case worse.
And also update cleanupAfterDeadshim, which makes sure that
cleanupAfterDeadshim must be called after shim disconnected. In some
case, shim fails to call runc-create for some reason, but the runc-create
already makes runc-init into ready state. If containerd doesn't call shim
deletion, the runc-init process will be leaky and hold the cgroup, which
makes pod terminating :(.

The changes needed by opencontainers/selinux are now in a tagged
release. This will make our dependency slightly ahead of what's
used by opencontainers/selinux until a v1.6.1 is tagged.
