Fix(test): resolve data race in StreamedRequest

[LukeAVanDrie]

What type of PR is this?

/kind test
/kind flake

What this PR does / why we need it:

This PR fixes a data race in the StreamedRequest integration test utility function. The race occurred due to unsynchronized access to a boolean flag used for timeout handling between the main test goroutine and a timer goroutine.

The fix replaces the boolean flag and timer goroutine with a channel and select statement. This ensures that communication between the goroutines is safe and prevents the data race, making the test suite more stable.

Which issue(s) this PR fixes:

Fixes #1718

Does this PR introduce a user-facing change?:

NONE

Hi @LukeAVanDrie. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@ahg-g I actually just pulled in the relevant fix from my open hermetic testing refactoring PR #1627 as that is still blocked on some other RCA work.
