Docker maps stdin to `/dev/null` which doesn't support epoll. Host FD
was ignoring the error and suceeding the epoll_ctl call from the
container, giving false impressing that epoll would be notified.
This required plumbing failure to all waiter.Waitable.EventRegister
callers and implementers.
Closes#6795

Our implementation of vfs.CheckDeleteSticky was not consistent with Linux,
specifically not consistent with fs/linux.h:check_sticky().
One of the biggest differences was that the vfs implementation did not
allow the owner of the sticky directory to delete files inside it that belonged
to other users.
This change makes our implementation consistent with Linux.
Also adds an integration test to check for this. This bug is also present in
VFS1.

This makes it easier to add more tests that run on Ubuntu. We can now just
add a bash script and call that from integration_test without having to set up
another image.

#5274 broke `make load-basic_fsstress` target. It works locally but for some
inconceivable reason it fails to build on Kokoro.

Copied the approach from the following issue to achieve the same goal:

This change allows Dockerfiles named Dockerfile.$(ARCH) and makes list-images
list only supported architectures.

9P2000.L is silent as to how readdir RPCs interact with directory mutation. The
most performant option is for Treaddir with offset=0 to restart iteration,
avoiding needing to walk+open+clunk a new directory fid between invocations of
getdents64(2), and the VFS2 gofer client assumes this is the case. Make this
actually true for the runsc fsgofer.

This change moves all Docker images to a standard location, and abstracts the
build process so that they can be maintained in an automated fashion. This also
allows the images to be architecture-independent.
All images will now be referred to by the test framework via the canonical
`gvisor.dev/images/<name>`, where `<name>` is a function of the path within the
source tree.
In a subsequent change, continuous integration will be added so that the images
will always be correct and available locally.
In the end, using `bazel` for Docker containers is simply not possible. Given
that we already have the need to use `make` with the base container (for
Docker), we extend this approach to get more flexibility.
This change also adds a self-documenting and powerful Makefile that is intended
to replace the collection of scripts in scripts. Canonical (self-documenting)
targets can be added here for targets that understand which images need to be
loaded and/or built.
