On Windows, the os/exec.{Command,CommandContext,LookPath} functions
resolve command names that have neither path separators nor file extension
(e.g., "git") by first looking in the current working directory before
looking in the PATH environment variable.
Go maintainers intended to match cmd.exe's historical behavior.
However, this is pretty much never the intended behavior and as an abundance of precaution
this patch prevents that when executing commands.
Example of commands that docker.exe may execute: `git`, `docker-buildx` (or other cli plugin), `docker-credential-wincred`, `docker`.
Note that this was prompted by the [Go 1.15.7 security fixes](https://blog.golang.org/path-security), but unlike in `go.exe`,
the windows path lookups in docker are not in a code path allowing remote code execution, thus there is no security impact on docker.

commit c2626a8270 replaced the use of
github.com/docker/docker/pkg/homedir with Golang's os.UserHomeDir().
This change was partially reverted in 7a279af43d
to account for situations where `$HOME` is not set.
In situations where no configuration file is present in `~/.config/`, the CLI
falls back to looking for the (deprecated) `~/.dockercfg` configuration file,
which was still using `os.UserHomeDir()`, which produces an error/warning if
`$HOME` is not set.
This patch introduces a helper function and a global variable to get the user's
home-directory. The global variable is used to prevent repeatedly looking up
the user's information (which, depending on the setup can be a costly operation).

Commit f32731f902 fixed a potential panic
when an error was returned while trying to get existing credentials.
However, other code paths currently use the result of `GetDefaultAuthConfig()`
even in an error condition; this resulted in a panic, because a `nil` was
returned.

The created time of the containerd is initialized with nanoseconds,
it seems to be a mistake.
In other places of the code, this field is initialized with seconds:
$ grep -rh 'time\.Now()\.Unix()' | grep Created
Created: time.Now().Unix(),
Created: time.Now().Unix(),
return []image.HistoryResponseItem{{ID: img, Created: time.Now().Unix()}}, nil
We can also see the the formatter assumes it to be seconds:
cli/command/formatter/container.go
----
func (c *ContainerContext) CreatedAt() string {
return time.Unix(c.c.Created, 0).String()
}
Interestingly, initializing the field with nanoseconds seems to work,
except on mips architecture, where it causes some kind of overflow.
