Remove SslHelper.isClientCertificateSupportAvailable()
The app's minSdkVersion = 15 (Android 4.0.3, Ice Cream Sandwich MR1),
so there's no need to test the API level.
This also removes '@SuppressLint("TrulyRandom")'. I find no
documentation for it, nor do I find any additional lint errors
with its removal.
