Android: Fix manifest parsing and APK names in export code

A better fix would be to make Godot's export code properly parse the
tag over multiple lines (and maybe even use XMLParser instead of doing
it ad-hoc?).

As for the APK names, we could alternatively pick the first .apk found
in the `debug` and `release` folders without expecting a specific name.

Fixes #32414.
