Enable NetworkConnectionHandler and AutoConnectHandler unittests in debug.

Enable NetworkConnectionHandler and AutoConnectHandler unittests in debug.

Speed improvements by using smaller certs/keys and probably because of the simpler pem/pk8 files instead of the pkcs12 should make these tests again fast enough for debug bots.

While there, replace usage of ScopedTestNSSChromeOSUser by the simpler ScopedTestNSSDB and remove the dependency on nss_util_internal.h.
