Android: Add 16 KiB page size support

So far, Dolphin hasn't been able to run on Android devices that use a
16 KiB page size. 16 KiB page sizes are a very new Android feature that
no phones have shipped with so far, so we're still compatible with the
phones that exist out there, but let's get this fixed before phones
start shipping with 16 KiB page sizes.

Because I couldn't get Android Studio's emulator to work, I haven't been
able to confirm that this change actually makes Dolphin fully compatible
with devices that use a 16 KiB page size. But I have confirmed that this
doesn't break anything on a regular 4 KiB page size device.
