In CL 517755 the test was added in the unconstrained os_test.go
because it appeared to be portable, but it turned out not to be
valid on plan9.
(The build error was masked on the misc-compile TryBots by #61923.)
Although the test can also compile and run on Windows, the bug it
checks for is specific to Linux and only really needs to run there, so
I am moving it to os_unix_test.go instead of adding yet another test
file for “Unix and Windows but not Plan 9”.
Updates #60181.

CL 497075 refactored NewFile to unconditionally dereference the file
returned by newFile. However, newFile can return nil if passed a
negative FD, which now causes a crash.
Resolve this by moving the invalid check earlier in NewFile, which also
lets us avoid a useless fcntl syscall on a negative FD.
Since we convert to int to check sign, adjust newFile to take an int
rather than uintptr, which cleans up a lot of conversions.
Fixes#60406

When these packages are released as part of Go 1.18,
Go 1.16 will no longer be supported, so we can remove
the +build tags in these files.
Ran go fix -fix=buildtag std cmd and then reverted the bootstrapDirs
as defined in src/cmd/dist/buildtool.go, which need to continue
to build with Go 1.4 for now.
Also reverted src/vendor and src/cmd/vendor, which will need
to be updated in their own repos first.

If an I/O operation fails because a deadline was exceeded,
return os.ErrDeadlineExceeded. We used to return poll.ErrTimeout,
an internal error, and told users to check the Timeout method.
However, there are other errors with a Timeout method that returns true,
notably syscall.ETIMEDOUT which is returned for a keep-alive timeout.
Checking errors.Is(err, os.ErrDeadlineExceeded) should permit code
to reliably tell why it failed.
This change does not affect the handling of net.Dialer.Deadline,
nor does it change the handling of net.DialContext when the context
deadline is exceeded. Those cases continue to return an error
reported as "i/o timeout" for which Timeout is true, but that error
is not os.ErrDeadlineExceeded.
