android: enable 64bit builds

android/README.md

 }
 ```
 
-Also, enable 32bit mode for react-native, since the react-native version we currently depend on only supports 32bit apps. (If you have a 64bit device, it will not run unless this setting it set).
-
-```gradle
-android {
-    ...
-    defaultConfig {
-        ndk {
-            abiFilters "armeabi-v7a", "x86"
-        }
-    }
-    ...
-```

 ### Build and use your own SDK artifacts/binaries

-            // The project react-native does not provide 64-bit binaries at the
-            // time of this writing. Unfortunately, packaging any 64-bit
-            // binaries into the .apk will crash the app at runtime on 64-bit
