wiringpi package needs update for RPi 4

[Don Stokes]

When I run the gpio utility, I see the following:

root@raspberrypi:~# gpio readall
Oops - unable to determine board type... model: 17

The output of the program should display information about the RPi board and GPIO status.

I am running Buster, updated this morning on 2019-10-22.

More Info:
