maintainers: fix app/test attributions

Two app/test entries were attributed to the wrong section:

* test_event_ring.c exercises rte_event_ring
  not the standalone app/test-eventdev/  binary.
  Move it from "Eventdev test application" to "Eventdev API"
  alongside test_eventdev.c, matching how test_event_eth_*_adapter.c and
  test_event_*_adapter.c are grouped with their corresponding
  lib/eventdev/*adapter* sub-libraries.

* The "test_*hash*" glob in the Hashes section unintentionally matched
  three crypto hash test vector headers which belong only
  to the Crypto API section. Replace with the two narrower globs
  "test_hash*" and "test_thash*" which together cover every legitimate
  hash test source (test_hash*.c and test_thash*.c) without leaking into
  cryptodev.
