Replaces #13037

Motivation

This test has an infrequent flake, see #13037

Modifications

The current test counts files in /tmp and hopes there are the same number before and after the test, which is fragile

Add a prefix to the stream temporary files.
Only count files in /tmp which have this prefix.

Verification

Tested locally. Tested with a file called /tmp/wfstream-asdfasd and extra logging in the test to show the numbers are as expected.
Tested with the os.Remove() removed from selfDestructingFile.Close() to show failure.

LGTM, replacement with os.CreateTemp deferred as it requires a more substantial refactor
