commandconn: fix race on `Close()`
During normal operation, if a `Read()` or `Write()` call results
in an EOF, we call `onEOF()` to handle the terminating command,
and store it's exit value.
However, if a Read/Write call was blocked while `Close()` is called
the in/out pipes are immediately closed which causes an EOF to be
returned. Here, we shouldn't call `onEOF()`, since the reason why
we got an EOF is because we're already terminating the connection.
This also prevents a race between two calls to the commands `Wait()`,
in the `Close()` call and `onEOF()`

Add a const for the name of the environment-variable we accept, so
that we can document its purpose in code.

Use the default proxy, to assist with vanity domains mis-behaving, but keep
a fallback for situations where we need to get modules from GitHub directly.
This should hopefully help with the gopkg.in/yaml.v2 domain often going AWOL;

From the Go documentation; https://go.dev/ref/mod#goproxy-protocol
> List elements may be separated by commas (,) or pipes (|), which determine error
> fallback behavior. When a URL is followed by a comma, the go command falls back
> to later sources only after a 404 (Not Found) or 410 (Gone) response. When a URL
> is followed by a pipe, the go command falls back to later sources after any error,
> including non-HTTP errors such as timeouts. This error handling behavior lets a
> proxy act as a gatekeeper for unknown modules. For example, a proxy could respond
> with error 403 (Forbidden) for modules not on an approved list (see Private proxy
> serving private modules).

the "golang.org/x/sys/execabs" package was introduced to address a security
issue on Windows, and changing the default behavior of os/exec was considered
a breaking change. go1.19 applied the behavior that was previously implemented
in the execabs package;
from the release notes: https://go.dev/doc/go1.19#os-exec-path
> Command and LookPath no longer allow results from a PATH search to be found
> relative to the current directory. This removes a common source of security
> problems but may also break existing programs that depend on using, say,
> exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe)
> in the current directory. See the os/exec package documentation for information
> about how best to update such programs.
>
> On Windows, Command and LookPath now respect the NoDefaultCurrentDirectoryInExePath
> environment variable, making it possible to disable the default implicit search
> of “.” in PATH lookups on Windows systems.
With those changes, we no longer need to use the execabs package, and we can
switch back to os/exec.

commit c846428cb6 added proxies to the
example `daemon.json`, based on the implementation that was added in
427c7cc5f8.
However, a follow-up pull request changed the proxy-configuration in`daemon.json`
to nest the configuration in a "proxies" struct, and the documentation was
not updated accordingly; see:

This patch fixes the example.
