[EME][OCDM] Prevent spurious keystatuses event when all keys expired
https://bugs.webkit.org/show_bug.cgi?id=315558
Reviewed by Xabier Rodriguez-Calvar.
If the keystore is empty, generating an empty status vector would trigger a new
keystatuses event
potentially overriding the previous one. Manually tested with a Widevine L3
CDM. This is sadly not
testable because there's no notion of key expiration in ClearKey.
Driving-by, improve GStreamer logging a bit in CDMProxyThunder.
