Update guava-jre instead of guava-android.

Since both flavors of Guava require Java 8+ nowadays (as [will jimfs](#229)), I don't think there's an advantage of using `guava-android`.

I suppose that I could look into how much of `java.file.nio` can work [under new versions of Android](https://developer.android.com/reference/java/nio/file/Path) or [with desugaring](https://developer.android.com/studio/write/java11-nio-support-table). (Notably, do custom file systems work at all?) But my guess is that, in general, any Android code that can use `java.file.nio` can use `guava-jre`—though perhaps it shouldn't do _either_ of those things :)
