Fix a problem that cert trust change needs a chrome restart to be effective.

This seems to be caused by CertVerifier's verification result cache.
- Added a new OnCertTrustChanged to CertDatabase::Observer;
- For NSS cert database, SetCertTrust triggers OnCertTrustChanged;
- Clear CertVerifier's result cache when OnCertDatabaseChanged is fired;

BUG=chromium-os:7988
TEST=Verify #2 issue in chromium-os:7988 where cert trust change only takes
effect after chrome restart.
