Android config fragment updated for Android 4.2

Hi Andrey

As part of the efforts to get Android 4.2 working I have added CONFIG_FUSE_FS to the android.conf in configs-core-tracking. Could you please consider pulling this into linux-linaro? Such a change should be innocuous and I've built and booted a vexpress Android kernel with this change.

I don't know if other Android builds are using config fragments or have their own defconfig, so perhaps they are also going to need updating...?
