Autoconfig - udev - Nintendo Switch N64 Controller

[damobeanrod]

Sorry I am unsure how to generate a PR for this... wasn't sure on the branching strategy. Hoping someone can review and merge...
https://github.com/libretro/retroarch-joypad-autoconfig/blob/master/udev/Nintendo%20Switch%20-%20N64%20Controller.cfg

Changes as follow

-  input_b_btn = "1" 
+ input_b_btn = "0" 

-  input_b_btn = "0"
+ input_y_btn = "1"

Input labels also reflected. This may be inaccurate the issue I resolved was for a Nintendo Switch Online N64 Controller using UDEV you must have input_y_btn defined for the "b" button to ever work. You can cross reference the "input_y_btn" existence in SDL for example. Which is what led me to this conclusion.
