Allow Android to ignore unnecessary joysticks (like fingerprint sensors)

[Nintorch]

Description

Previously, SDL_ShouldIgnoreJoystick wasn't being called for Android, and fingerprint sensors were recognized as joysticks. I also decided to change the code a little bit so other fingerprint sensors (possible fingerprint sensors list here: godotengine/godot#47656 (comment)) are ignored too. This change was tested using Godot Engine in my fork in a separate branch: https://github.com/Nintorch/godot/tree/sdl-test and I can confirm it works as expected.

I have a Pixel 5. Why am I not seeing the fingerprint sensor as a joystick?

Hi, if you mean you're not seeing your fingerprint sensor as a joystick without this PR, that's interesting, because for me the fingerprint sensor on my phone (Xiaomi Redmi Note 11) does get recognized (as "uinput-fpc")

Yes, that's what I mean. I've never seen a finger print scanner be enumerated as a joystick on Android. Tested on Pixel 5, and several Samsung phones. I'm using the latest SDL3 from source.

Maybe it's a certain Android version that does this?

If you like, I can step through the Java code where SDL enumerates devices and see what's going on?

My phone currently uses Android 13, and, for more context, this bug was found while I was working on one of my Godot Engine PRs ( godotengine/godot#109645 specifically), Godot Engine currently uses SDL 3.2.16.

If you like, I can step through the Java code where SDL enumerates devices and see what's going on?

Sure, thank you!

Merged and cherry-picked, thanks!

Thank you! :)
