Android: build failure with ndk 27-beta1 due to use of deprecated ALooper_pollAll

[madebr]

Building SDL3 with ndk 27-beta1 fails with the following error:

/home/maarten/projects/SDL/src/sensor/android/SDL_androidsensor.c:73:13: error: 'ALooper_pollAll' is unavailable: obsoleted in Android 1
   73 |         if (ALooper_pollAll(-1, NULL, &events, (void **)&source) == LOOPER_ID_USER) {
      |             ^

Configuring with -DCMAKE_C_FLAGS="-Wno-error=deprecated" -DSDL_WERROR=OFF does not turn the error in a warning.

ALooper_pollAll documentation

android/ndk#2020 this seems to be the proper handling, suggested by the ndk maintainers, to be used to replace poolAll with poolOnce

I rolled back to NDK 25.1.8937393 for this reason.

Looks like github runners are removing NDK 25 very soon: actions/runner-images#10342. While trying to compile 2.30.6, I started seeing this issue:

./src/sensor/android/SDL_androidsensor.c:164:9: error: 'ALooper_pollAll' is unavailable: obsoleted in Android 1 - ALooper_pollAll may ignore wakes. Use ALooper_pollOnce instead. See The API documentation for more information

This is fixed for the next release in 4222ceb, thanks!
