test: use common/tmpdir in watch-mode ipc test
Browse files Browse the repository at this point in the history
Using `path.join(os.tmpdir(), 'file')` on a multi-user system can lead
to file collisions where the file already exists but is owned by a
different user and cannot be removed or overwritten. Other tests in
`parallel/test-watch-mode-files_watcher` use `common/tmpdir` instead
so switch to that for consistency.
