Prevent dangling cat-file calls (goroutine alternative) (#19454)
If an `os/exec.Command` is passed non `*os.File` as an input/output, go
will create `os.Pipe`s and wait for their closure in `cmd.Wait()`.  If
the code following this is responsible for closing `io.Pipe`s or other
handlers then on process death from context cancellation the `Wait` can
hang.

There are two possible solutions:

1. use `os.Pipe` as the input/output as `cmd.Wait` does not wait for these.
2. create a goroutine waiting on the context cancellation that will close the inputs.

This PR provides the second option - which is a simpler change that can
be more easily backported.

Closes #19448
