fsmonitor: fix hashmap memory leak in fsmonitor_run_daemon
The `state.cookies` hashmap is initialized during daemon startup but never freed during cleanup in the `done:` label of fsmonitor_run_daemon(). The cookie entries also have names allocated via strbuf_detach() that must be freed individually. Iterate the hashmap to free each cookie name, then call hashmap_clear_and_free() to release the entries and table.
