evdev: ignore BTN_TOUCH, support SDL_TOUCH_MOUSEID and pressure.

Silence warning about EVDEV KeyCode 330 (BTN_TOUCH) when pressing or releasing touchscreen.[1]
Add support for touchscreen mouse emulation using SDL_TOUCH_MOUSEID to SDL_evdev.
Add unverified support for touchscreen pressure to SDL_evdev.

Tested on Raspbian Stretch with the official Raspberry Pi 7" touchscreen (no pressure support).
