Subject: [PATCH] Fix racy tests sharing tests/data.out

streams_001, streams_002 and streams_004 all write, stat and unlink the very
same file tests/data.out. Since php-src 1d2ea5ce22c ("Run tests in parallel by
default", GH-22939, first released in php-8.6.0beta1) run-tests.php spawns
min(nproc, 10) workers by default, so these three tests race each other and
fail intermittently - filesize()/file_get_contents() hit a path a sibling test
has just unlinked.

Give each test its own scratch file, the way tests/dictionary_streams.phpt
already does.
