run-tests: Clean the file cache directory in --file-cache-prime (#22784)

`run-tests.php --file-cache-prime` sets opcache.file_cache to /tmp which makes it difficult to clear the cache.

Set opcache.file_cache to /tmp/php-run-tests-file-cache, and clear the directory when --file-cache-prime is specified.

Changed paths:
  M  run-tests.php
