SwiftShell fails to compile with Xcode 12 beta

[Belcarra]

Moving to Xcode 12 / Big Sur Beta, trying to see if Karabiner would build properly.

SwiftShell is causing a problem.

Karabiner-DriverKit-VirtualHIDDevice can now be built on Xcode 12.

A provisioning profile which supports com.apple.developer.driverkit is required to build a driver extension since Xcode 12. https://github.com/pqrs-org/Karabiner-DriverKit-VirtualHIDDevice#note
