Subject: [PATCH] test: Use AUDIO_F32SYS for native-endianness

AUDIO_F32 is an alias for AUDIO_F32LSB, 32-bit floating point with least
significant byte first, resulting in audio_resampleLoss() failing on
big-endian machines. This particular test generates a buffer with
native-endianness float values, so it ought to be using AUDIO_F32SYS,
which is 32-bit floating point in the native endianness.

Already fixed by commit 47bcb078 "Fixed some incorrect SDL_AUDIO_F32 uses"
on the SDL 3 branch.
