util: fix logging to be compatible with Android for AdvancedTlsX509KeyManager

[danielzhaotongliu]

• Previous java.util.logging.Logger#log() usage in AdvancedTlsX509KeyManager.java was newly introduced in API level 26 not backwards compatible with Android

Since it is severe, we're not too concerned about it not actually logging. If we become concerned later, we'll just add the normal "if log level is on" check.

Thanks for catching this! Yeah I see that the method was added in 26 - https://developer.android.com/sdk/api_diff/26/changes/java.util.logging.Logger
Did you catch it using some tests that I missed to run?
