fix(build): correct event-stream-compat import path in watch-win32.ts

build/lib/watch/watch-win32.ts imported './event-stream-compat.ts' which
resolves to build/lib/watch/event-stream-compat.ts — a path that does not
exist.  The file lives one directory up at build/lib/event-stream-compat.ts,
so the import must be '../event-stream-compat.ts'.
