Silence NewApi lint warnings
Java code is linted with build/android/AndroidManifest.xml which
currently still uses minSdkVersion=14 (ICS). Code under android_webview
will only ship on 22 (L) or later in production. And android webview
instrumentation tests only run on 19 (K) or later. So there is not even
any requirement to add run time checks for these APIs.
Just silence them with SuppressLint.
