What area of the game / PPSSPP

Upon running PPSSPP on the first time, with a non-existent ppsspp.ini, on the terminal output we get;

then it returns to the prompt. The ini now has

Rerunning PPSSPPSDL a subsequent time gets us

This will constantly happen until the user goes into the ppsspp.ini and edits GraphicsBackend to 3 (VULKAN). Despite the failed backend being listed in the ini, it is still accessible in the UI and able to be selected thereby reverting the manual change and forcing the user to repeat the process.

What should happen

If OpenGL is PPSSPP's hard coded default on Linux, it should attempt to cycle through the alternative backends (vulkan being the only other available on at writing).
If a backend fails, should it not be marked disabled in DisabledGraphicsBackends, until next restart of PPSSPP when it can test the backend?
