[Feature Request] Support for Bliss Box API on Linux

[syboxez]

According to ulao and also my personal testing on my 4-Play on the latest firmware, RetroArch only supports the Bliss-Box detection API on Windows and not Linux.

Notable quote from ulao: "Just for the info, what they said was that in lib USB they couldn't do control transfers like they could with win USB"

I have also tested alternate autoconfig profiles provided by hunterk on Discord that were updated to support the 3.x firmwares, and I have also tried commenting out the device names in all the profiles. What ends up happening is my controller is recognized as an Atari controller, but I can still manually map the buttons. I believe this is because the Atari profile alphanumerically comes first, although I may be wrong there.

I am using Arch Linux with the udev controller driver.
