Fix classification script to work around qualcomm disabling SVE on their chips

[Sonicadvance1]

Causes things compiled through AUR or native with default classification to SIGILL at the start. Need to check for enabled features through cpuinfo or cpuid flags and work around that.

https://github.com/FEX-Emu/FEX/blob/main/Scripts/aarch64_fit_native.py This is the script
https://github.com/FEX-Emu/FEX/blob/main/CMakeLists.txt#L357-L394 Where it gets utilized.

Should be able to do something like -mcpu=cortex-x4,-sve to remove the sve feature or something.
